Description

本発明はタッチパネル及びその製造技術に関する。 The present invention relates to a touch panel and a manufacturing technique thereof.

従来より、タッチパネルはＰＤＡ（ＰｅｒｓｏｎａｌＤｉｇｉｔａｌＡｓｓｉｓｔａｎｃｅ）やコピー機等のオペレーションパネルに広く用いられている。 Conventionally, touch panels have been widely used for operation panels such as PDAs (Personal Digital Assistance) and copiers.

図７の符号１０１は従来技術のタッチパネルの一例を示しており、このタッチパネル１０１は、第一、第二の基板１１０、１２０とが貼り合わされた積層体１０２と、ＬＣＤ（ＬｉｑｕｉｄＣｒｙｓｔａｌＤｉｓｐｌａｙ）のような表示装置１３０とを有しており、積層体１０２は第一の基板１１０が配置された側の面が表示装置１３０に貼り合わされている。 Reference numeral 101 in FIG. 7 shows an example of a conventional touch panel. The touch panel 101 includes a laminated body 102 in which first and second substrates 110 and 120 are bonded together, and an LCD (Liquid Crystal Display). The laminated body 102 is bonded to the display device 130 on the surface on which the first substrate 110 is disposed.

第一、第二の基板１１０、１２０は第一、第二の樹脂フィルム１１１、１２１と、第一、第二の樹脂フィルム１１１、１２１上に配置された第一、第二の電極膜１１２、１２２とを有しており、第一、第二の樹脂フィルム１１１、１２１と、第一、第二の電極膜１１３、１２３はそれぞれ透明な材質で構成されているため、表示装置１３０で表示される画像情報は、第二の基板１２０側から観察可能になっている。 The first and second substrates 110 and 120 are first and second resin films 111 and 121, and first and second electrode films 112 disposed on the first and second resin films 111 and 121, respectively. 122, and the first and second resin films 111 and 121 and the first and second electrode films 113 and 123 are each made of a transparent material, and are therefore displayed on the display device 130. The image information can be observed from the second substrate 120 side.

第一、第二の電極膜１１２、１２２は第一、第二の基板１１０、１２０の互いに対向する面にそれぞれ配置されており、情報を入力しない非入力状態では、第一、第二の基板１１０、１２０は互いに離間しており、第一、第二の電極膜１１２、１２２は電気的に接続されていないが、表示装置１３０の画像情報により選択した部分を第二の基板１２０側から押圧すると、第一の基板１１０のスペーサ１１８が、第二の電極膜１２２の表面に接触し、押圧された部分で第一、第二の電極膜１１２、１２２が電気的に接続される。このとき、第一、第二の電極膜１１２、１２２の電位変化を測定すれば、押圧された箇所特定し、入力情報として処理することができる。 The first and second electrode films 112 and 122 are disposed on the mutually opposing surfaces of the first and second substrates 110 and 120, respectively, and in the non-input state where information is not input, the first and second substrates 110 and 120 are separated from each other, and the first and second electrode films 112 and 122 are not electrically connected, but the portion selected by the image information of the display device 130 is pressed from the second substrate 120 side. Then, the spacer 118 of the first substrate 110 comes into contact with the surface of the second electrode film 122, and the first and second electrode films 112 and 122 are electrically connected at the pressed portion. At this time, if the potential change of the first and second electrode films 112 and 122 is measured, the pressed portion can be identified and processed as input information.

上述したようなタッチパネル１０１では、一般に、積層体１０２と表示装置１３０のいずれか一方に接着フィルム１２９を貼付し、押圧ロールによって積層体１０２を表示装置１３０に押し当てながら移動させることで、積層体１０２を表示装置１３０に貼り合わせている。 In the touch panel 101 as described above, in general, the adhesive film 129 is attached to one of the laminate 102 and the display device 130, and the laminate 102 is moved while being pressed against the display device 130 by a pressing roll, whereby the laminate 102 is bonded to the display device 130.

ところで、第一、第二の基板１１０、１２０は、外周近傍に配置されたリング状の接着剤１２７によって互いに貼付されており、少なくともその接着剤１２７の膜厚分だけ互いに離間し、押圧空間１３９が形成されている。 By the way, the first and second substrates 110 and 120 are attached to each other by a ring-shaped adhesive 127 disposed in the vicinity of the outer periphery, separated from each other by at least the film thickness of the adhesive 127, and pressed space 139. Is formed.

このような積層体１０２を表示装置１３０に貼付する際には、積層体１０２の押圧空間１３９が位置する部分を押圧するときに、押圧空間１３９に存する空気の反発力によって積層体１０２と表示装置１３０の密着性が悪くなり、積層体１０２表面の接着剤１２９と表示装置１３０との間に空気溜りが発生する場合がある。 When such a laminate 102 is affixed to the display device 130, when the portion of the laminate 102 where the pressing space 139 is located is pressed, the laminate 102 and the display device are repelled by the repulsive force of air existing in the pressing space 139. The adhesiveness of 130 may deteriorate, and an air pocket may be generated between the adhesive 129 on the surface of the laminate 102 and the display device 130.

接着剤１２９と表示装置１３０との間に空気溜りがあると、第二の基板１２０側から観察される表示装置１３０の画像が歪んで見える原因となる。 If there is an air pocket between the adhesive 129 and the display device 130, an image of the display device 130 observed from the second substrate 120 side may be distorted.

第一、第二の基板１１０、１２０を貼り合わせる接着剤１２７に押圧空間１３９と外部空間とを接続する空気孔１１９を形成しておけば、押圧ロールで積層体１０２を押圧するときに、押圧空間１３９の空気が外部に抜けるので、接着剤１２９と表示装置１３０との密着性が高くなる。 If an air hole 119 that connects the pressing space 139 and the external space is formed in the adhesive 127 that bonds the first and second substrates 110 and 120, the pressing is performed when the laminate 102 is pressed with a pressing roll. Since the air in the space 139 escapes to the outside, the adhesiveness between the adhesive 129 and the display device 130 is improved.

しかしながら、接着剤１２７に空気孔１１９を設けると、出来上がりのタッチパネル１の内部空間に、外部空間から埃や水分が浸入する恐れがあり、故障の原因となる場合がある。積層体１０２を表示装置１３０に貼り合わせた後、空気孔１１９の開口を封止樹脂等により塞ぐことも可能であるが、空気孔１１９を完全に塞ぐことは困難であり、また、工程数が増えるため製造コストも高くなる。
実公平７−１６２６６特開平７−３１４５９７特開２００１−２１８７１特開２００２−５５３３０ However, if the air holes 119 are provided in the adhesive 127, dust and moisture may enter the internal space of the finished touch panel 1 from the external space, which may cause a failure. After the laminated body 102 is bonded to the display device 130, the opening of the air hole 119 can be closed with a sealing resin or the like, but it is difficult to completely close the air hole 119, and the number of steps is small. Increased manufacturing costs also increase.

以下で図面を参照し、本発明の実施形態について説明する。
図３の符号１は本発明のタッチパネルを示しており、タッチパネル１は第一、第二の基板１０、２０と、貼付対象物３０とを有している。 Embodiments of the present invention will be described below with reference to the drawings.
Reference numeral 1 in FIG. 3 represents the touch panel of the present invention, and the touch panel 1 includes first and second substrates 10 and 20 and a pasting object 30.

図１（ａ）と、図２（ａ）はそれぞれ第一、第二の基板１０、２０を示す断面図であり、第一、第二の基板１０、２０は第一、第二の樹脂フィルム１１、２１と、第一、第二の樹脂フィルム１１、２１の表面に全面成膜された第一、第二の電極膜１２、２２と、第一、第二の電極膜１２、２２の外周近傍に形成された第一、第二の下部絶縁層１３、２３と、第一、第二の下部絶縁層１３、２３上に形成され、第一、第二の下部絶縁層１３、２３によって第一、第二の電極膜１２、２３から絶縁された第一、第二の配線膜１４、２４とを有している。 FIG. 1A and FIG. 2A are cross-sectional views showing the first and second substrates 10 and 20, respectively. The first and second substrates 10 and 20 are the first and second resin films, respectively. 11, 21, first and second electrode films 12, 22 formed on the entire surface of the first and second resin films 11, 21, and outer circumferences of the first and second electrode films 12, 22 The first and second lower insulating layers 13 and 23 formed in the vicinity, and the first and second lower insulating layers 13 and 23, and the first and second lower insulating layers 13 and 23 The first and second wiring films 14 and 24 are insulated from the first and second electrode films 12 and 23.

第一、第二の下部絶縁層１３、２３の所定位置には不図示の開口が形成されており、開口が形成された部分では第一、第二の配線膜１４、２４が第一、第二の電極膜１２、２２に電気的に接続されている。 Openings (not shown) are formed at predetermined positions of the first and second lower insulating layers 13 and 23, and the first and second wiring films 14 and 24 are formed in the first and second portions in the portions where the openings are formed. The second electrode films 12 and 22 are electrically connected.

第一、第二の配線膜１４、２４の上には第一、第二の上部絶縁層１５、２５が配置されており、第一、第二の下部絶縁層１３、２３と、第一、第二の配線膜１４、２４と、第一、第二の上部絶縁層１５、２５とが積層された多層体はリング状になっている。 First and second upper insulating layers 15 and 25 are disposed on the first and second wiring films 14 and 24, and the first and second lower insulating layers 13 and 23, The multilayer body in which the second wiring films 14 and 24 and the first and second upper insulating layers 15 and 25 are laminated has a ring shape.

第一の基板１０では多層体の内側に第一の電極膜１２上に形成されたスペーサ１８が露出し、第二の基板２０では多層体の内側に第二の電極膜２２の表面が露出しており、第一、第二の基板１０、２０は後述するように、第一、第二の上部絶縁層１５、２５のいずれか一方又は両方に第一の接着剤２７を配置した状態で、スペーサ１８と第二の電極膜２２の露出部分とが互いに対向するように貼り合わされ、積層体２が形成されている。 In the first substrate 10, the spacer 18 formed on the first electrode film 12 is exposed inside the multilayer body, and in the second substrate 20, the surface of the second electrode film 22 is exposed inside the multilayer body. The first and second substrates 10 and 20 have a first adhesive 27 disposed on either one or both of the first and second upper insulating layers 15 and 25, as will be described later. The spacer 18 and the exposed portion of the second electrode film 22 are bonded together so as to face each other, so that the stacked body 2 is formed.

ここでは、貼着対象物３０はＬＣＤ（ＬｉｑｕｉｄＣｒｙｓｔａｌＰａｎｅｌ）のような表示装置で構成されている。後述するように、積層体２は、第一の基板１０の表面に第二の接着剤２９が貼付されており、積層体２は、その第二の接着剤２９の表面が表示装置３０は画像を表示する表示面３５に密着されて貼付されている。 Here, the sticking object 30 is composed of a display device such as an LCD (Liquid Crystal Panel). As will be described later, the laminate 2 has a second adhesive 29 attached to the surface of the first substrate 10, and the laminate 2 has an image of the display device 30 on the surface of the second adhesive 29. Is attached in close contact with the display surface 35 for displaying.

ここでは、第一の樹脂フィルム１１は等方性フィルムで構成されている。第二の接着剤２９は透明な接着剤で構成され、第一、第二の電極膜１２、２２はＩＴＯ（インジウム錫酸化物）膜のような透明導電膜で構成されており、表示面３５から放射される光は、第二の接着剤２９を通過し、第一の樹脂フィルム１１を復屈折せずに通過した後、更に第一の電極膜１２を通過する。 Here, the first resin film 11 is made of an isotropic film. The second adhesive 29 is made of a transparent adhesive, and the first and second electrode films 12 and 22 are made of a transparent conductive film such as an ITO (indium tin oxide) film. The light radiated from the light passes through the second adhesive 29, passes through the first resin film 11 without being refracted, and then passes through the first electrode film 12.

第一の電極膜１２を通過した光は上述した多層体と第一の接着剤２７とを通過せずに吸収されるが、多層体と第一の接着剤２７と、第一、第二の電極膜１２、２２とで囲まれた押圧空間３９を通過し、押圧空間３９真上位置で第二の電極膜２２を通過する。 The light that has passed through the first electrode film 12 is absorbed without passing through the multilayer body and the first adhesive 27, but the multilayer body, the first adhesive 27, and the first and second adhesives are absorbed. It passes through the press space 39 surrounded by the electrode films 12 and 22 and passes through the second electrode film 22 at a position directly above the press space 39.

ここでは、積層体２の第二の基板２０が配置された側の面には偏光板３２が貼付されている。第二の樹脂フィルム２１は位相差フィルムで構成されており、第二の電極膜２２を通過した光は第二の樹脂フィルム２１で偏光板３２に対する光学的なずれが補正された後、偏光板３２に吸収されることなく外部に放出される。 Here, the polarizing plate 32 is affixed to the surface of the laminated body 2 on which the second substrate 20 is disposed. The second resin film 21 is composed of a retardation film, and the light that has passed through the second electrode film 22 is corrected for optical deviation with respect to the polarizing plate 32 by the second resin film 21. 32 is released to the outside without being absorbed.

これに対し、タッチパネル１に入射する外光は、偏光板３２を透過したとしても、第二の樹脂フィルム２１を透過し、表示面３５で反射された後、再び第二の樹脂フィルム２１を透過することで入射時とは逆方向に偏光されるので、外部に放出されることなく偏光板３２に吸収される。従って、このタッチパネル１では外光反射が少なく、表示装置３０で表示される画像が偏光板３２側から鮮明に観察される。 On the other hand, even if the external light incident on the touch panel 1 passes through the polarizing plate 32, it passes through the second resin film 21, is reflected by the display surface 35, and then passes through the second resin film 21 again. As a result, the light is polarized in the direction opposite to that at the time of incidence, and is absorbed by the polarizing plate 32 without being emitted to the outside. Accordingly, the touch panel 1 has little external light reflection, and an image displayed on the display device 30 is clearly observed from the polarizing plate 32 side.

尚、偏光板３２の表面には、透明なハードコート層４３を有する透明なＰＥＴ（ポリエチレンテレフタレート）樹脂フィルム４２が透明な接着剤層４１を介して貼付されており、偏光板３２はこのハードコート層４３とＰＥＴ樹脂フィルム４２とからなるオーバーコート３３によって外部衝撃から保護される。 A transparent PET (polyethylene terephthalate) resin film 42 having a transparent hard coat layer 43 is attached to the surface of the polarizing plate 32 via a transparent adhesive layer 41. The overcoat 33 composed of the layer 43 and the PET resin film 42 is protected from external impact.

次に、このタッチパネル１を用いて情報を入力する工程について説明する。入力者はタッチパネル１の偏光板３２側の面から、表示装置３０によって表示される画像を観察し、その画像情報によって選択した位置を指やペン等の入力手段によって偏光板３２側から押圧する。 Next, a process for inputting information using the touch panel 1 will be described. The input person observes the image displayed by the display device 30 from the surface of the touch panel 1 on the side of the polarizing plate 32, and presses the position selected by the image information from the side of the polarizing plate 32 by an input means such as a finger or a pen.

第一の電極膜１２の表面には複数個のスペーサ１８が所定間隔を空けて配置されており、各スペーサ１８の高さは、第一、第二の電極膜１２、２２との間の距離よりも低いので、タッチパネル１が押圧されないときには、スペーサ１８の先端は第二の電極膜２２の表面から離間しているが、タッチパネル１を積層体２の第二の基板２０側から押圧し、第二の基板２０の押圧された部分が曲がると、押圧された位置で第二の電極膜２２がスペーサ１８の先端に接触する。 A plurality of spacers 18 are arranged on the surface of the first electrode film 12 at a predetermined interval, and the height of each spacer 18 is the distance between the first and second electrode films 12 and 22. When the touch panel 1 is not pressed, the tip of the spacer 18 is separated from the surface of the second electrode film 22, but the touch panel 1 is pressed from the second substrate 20 side of the laminate 2, When the pressed portion of the second substrate 20 bends, the second electrode film 22 contacts the tip of the spacer 18 at the pressed position.

各スペーサ１８は導電性樹脂で構成されており、第一の電極膜１２と電気的に接続されているので、第二の電極膜２２がスペーサ１８と接触すると、第一、第二の電極膜１２、２２が押圧された位置で電気的に接続される。 Since each spacer 18 is made of a conductive resin and is electrically connected to the first electrode film 12, when the second electrode film 22 contacts the spacer 18, the first and second electrode films 12 and 22 are electrically connected at the pressed position.

第一、第二の配線膜１４、２４は不図示の分析装置に接続され、該分析装置により第一の第二の配線膜１４、２４へ電流を供給すると同時に、その電位変化を測定可能になっており、上述したように第一、第二の配線膜１４、２４はそれぞれ第一、第二の電極膜１２、２２に電気的に接続されているので、押圧したときの電位変化を検出することで、第一、第二の電極膜１２、２２が電気的に接続された位置が特定され、入力情報として処理される。 The first and second wiring films 14 and 24 are connected to an analysis device (not shown), and the current can be supplied to the first second wiring films 14 and 24 by the analysis device, and at the same time the potential change can be measured. As described above, since the first and second wiring films 14 and 24 are electrically connected to the first and second electrode films 12 and 22, respectively, the potential change when pressed is detected. As a result, the position where the first and second electrode films 12 and 22 are electrically connected is specified and processed as input information.

次に、このタッチパネル１を製造する工程について説明する。先ず、第一の樹脂フィルム１１上にスパッタ法等により第一の電極膜１２を成膜する。次いで、第一の電極膜１２表面の第一の樹脂フィルム１１端部から所定距離だけ内側の領域に、スクリーン印刷法で導電性樹脂からなる複数個のスペーサ１８を所定間隔を空けて形成する。 Next, a process for manufacturing the touch panel 1 will be described. First, the first electrode film 12 is formed on the first resin film 11 by sputtering or the like. Next, a plurality of spacers 18 made of a conductive resin are formed at a predetermined interval in a region on the surface of the first electrode film 12 that is a predetermined distance from the end of the first resin film 11 by a screen printing method.

次に、スクリーン印刷法によりスペーサ１８が形成された領域を取り囲むように絶縁性樹脂を塗布してリング状の第一の下部絶縁層１３を形成し、第一の下部絶縁層１３の内周端部よりも所定距離だけ外側の位置にスクリーン印刷法により銀ペーストからなる第一の配線膜１４と、絶縁樹脂からなる第一の上部絶縁層１５とを形成すると、図１（ａ）に示すような第一の基板１０が得られる。 Next, an insulating resin is applied so as to surround the region where the spacers 18 are formed by screen printing to form a ring-shaped first lower insulating layer 13, and the inner peripheral edge of the first lower insulating layer 13 When a first wiring film 14 made of silver paste and a first upper insulating layer 15 made of insulating resin are formed by a screen printing method at a position outside a predetermined distance from the portion, as shown in FIG. A first substrate 10 is obtained.

次に、接着フィルムからなる第二の接着剤２９を、第一の基板１０の第一の樹脂フィルム１１が配置された側の面に貼付し、第一の下部絶縁層１３の内周端部と、第一の配線膜１４との間の位置で、第一の基板１０と、第二の接着剤２９を穿設すると、第一の樹脂フィルム１１と、第一の電極膜１２と、第一の下部絶縁層１３とを貫通する空気孔１９と、第二の接着剤２９を貫通し、該空気孔１９と連通する貫通孔２８とが同時に形成される（図１（ｂ））。 Next, the 2nd adhesive agent 29 which consists of adhesive films is affixed on the surface by which the 1st resin film 11 of the 1st board | substrate 10 is arrange | positioned, and the inner peripheral edge part of the 1st lower insulating layer 13 When the first substrate 10 and the second adhesive 29 are punched at a position between the first wiring film 14 and the first wiring film 14, the first resin film 11, the first electrode film 12, An air hole 19 penetrating through one lower insulating layer 13 and a through hole 28 penetrating through the second adhesive 29 and communicating with the air hole 19 are simultaneously formed (FIG. 1B).

次に、両面粘着テープからなるリング状の第一の接着剤２７を用意し、該第一の接着剤を、空気孔１９の開口が位置し、かつスペーサ１８が形成された領域が露出するように第一の上部絶縁層１５表面に貼付する（図１（ｃ））。 Next, a ring-shaped first adhesive 27 made of a double-sided pressure-sensitive adhesive tape is prepared, and the first adhesive is exposed so that the opening of the air hole 19 is located and the region where the spacer 18 is formed is exposed. Affixed to the surface of the first upper insulating layer 15 (FIG. 1C).

これとは別に図２（ａ）に示した第二の基板２０の、第二の樹脂フィルム２１が配置された側の面に、透明な第三の接着剤３４を介して偏光板３２を貼付し、更に上述したオーバーコート３３を透明な接着剤層４１を介して貼付する。図２（ｂ）はオーバーコート３３が第二の基板２０に貼付された状態を示している。 Separately, a polarizing plate 32 is attached to the surface of the second substrate 20 shown in FIG. 2A on the side on which the second resin film 21 is disposed via a transparent third adhesive 34. Further, the overcoat 33 described above is pasted through the transparent adhesive layer 41. FIG. 2B shows a state where the overcoat 33 is attached to the second substrate 20.

その第二の基板２０の電極膜２２が露出する面と、第一の基板１０のスペーサ１８が露出する面とを対向させて位置合わせを行い、第二の上部絶縁層２５を第一の接着剤２７に密着させると、第一、第二の基板１０、２０が貼り合わされ、図１（ｄ）に示すような積層体２が構成される。 The surface of the second substrate 20 where the electrode film 22 is exposed and the surface of the first substrate 10 where the spacer 18 is exposed are opposed to perform alignment, and the second upper insulating layer 25 is bonded to the first. When brought into close contact with the agent 27, the first and second substrates 10 and 20 are bonded together, and the laminate 2 as shown in FIG.

この状態では、空気孔１９の開口と、スペーサ１８とが位置する領域が、第一の接着剤２７と、第二の基板２０とで取り囲まれて押圧空間３９が構成されており、この押圧空間３９は空気孔１９と、空気孔１９に連通する貫通孔２８によって積層体２の外部空間に接続されている。 In this state, the area where the opening of the air hole 19 and the spacer 18 are located is surrounded by the first adhesive 27 and the second substrate 20 to form a pressing space 39. Reference numeral 39 denotes an air hole 19 and a through hole 28 communicating with the air hole 19 and is connected to the external space of the laminate 2.

次に、この積層体２を表示装置３０に貼り付ける工程について説明する。図４の符号９０は積層体２を表示装置３０に貼り付ける貼り合わせ装置の一例を示しており、この貼り合わせ装置９０は下部プレート９１と上部プレート９５とを有している。 Next, a process of attaching the laminate 2 to the display device 30 will be described. Reference numeral 90 in FIG. 4 shows an example of a laminating apparatus for laminating the laminate 2 to the display device 30, and the laminating apparatus 90 includes a lower plate 91 and an upper plate 95.

上部プレート９５はアルミニウム等の金属で構成されているのに対し、下部プレート９１の上部プレート９５と対向する載置面９４は伸縮性の樹脂フィルム（例えば、８０〜３００メッシュのポリエステル樹脂フィルム）で構成されており、下部プレート９１内部に配置された押圧ロール９３を押し上げると、載置面９４を構成する樹脂フィルムが持ち上げられるようになっている。 The upper plate 95 is made of a metal such as aluminum, whereas the mounting surface 94 of the lower plate 91 facing the upper plate 95 is an elastic resin film (for example, an 80-300 mesh polyester resin film). The resin film which comprises the mounting surface 94 is lifted when the press roll 93 arrange | positioned inside the lower plate 91 is pushed up.

先ず、積層体２を第二の接着剤２９が配置された側の面を上側に向けた状態で下部プレート９１の載置面９４上に載せ、表示装置３０を表示面を下側に向けた状態で上部プレート９５に保持させ、積層体２と表示装置３０の位置合わせを行う。 First, the laminate 2 is placed on the placement surface 94 of the lower plate 91 with the surface on which the second adhesive 29 is disposed facing upward, and the display device 30 is directed downward. In this state, the upper plate 95 is held, and the stacked body 2 and the display device 30 are aligned.

この状態では、積層体２は貼着対象物３０から離間しているが、押圧ロール９３を持ち上げると、押圧ロール９３が樹脂フィルムを挟んで積層体２の端部を表示装置３０に押圧し、積層体２０の押圧された部分が表示装置３０に貼付される。 In this state, the laminated body 2 is separated from the object to be adhered 30, but when the pressing roll 93 is lifted, the pressing roll 93 presses the end of the laminated body 2 against the display device 30 with the resin film interposed therebetween, The pressed portion of the laminate 20 is attached to the display device 30.

積層体２を押圧しながら押圧ロール９３を空気孔１９が位置する端部に向かって移動させると、積層体２の押圧ロール９３が通過した部分は第二の接着剤２９によって表示装置３０に貼着されるので、表示装置３０に密着した状態が維持されるが、積層体２の押圧ロール９３が通過していない部分は自重により表示装置３０から離間し、空気孔１９は塞がれていない。 When the pressing roll 93 is moved toward the end where the air holes 19 are located while pressing the laminated body 2, the portion of the laminated body 2 through which the pressing roll 93 has passed is pasted to the display device 30 by the second adhesive 29. Since it is attached, the state of being in close contact with the display device 30 is maintained, but the portion of the laminate 2 where the pressing roll 93 does not pass is separated from the display device 30 by its own weight, and the air holes 19 are not blocked. .

従って、押圧ロール９３が積層体２の押圧空間３９を通過するときには、押圧によって押し退けられた押圧空間３９の空気は、空気孔１９を通って外部空間に押し出されるので、押圧空間３９が密閉されている場合に比べて押圧ロール９３にかかる反発力が小さく、第二の基板２０は第一の基板１０に押し付けられ、第二の電極膜２２がスペーサ１８に接触する。 Therefore, when the pressing roll 93 passes through the pressing space 39 of the laminated body 2, the air in the pressing space 39 pushed away by pressing is pushed out to the external space through the air holes 19, so that the pressing space 39 is sealed. The repulsive force applied to the pressing roll 93 is small as compared with the case where the second substrate 20 is pressed against the first substrate 10, and the second electrode film 22 contacts the spacer 18.

第二の電極膜２２がスペーサ１８に接触すると、第二の電極膜２２とスペーサ１８とが離間しているときに比べて積層体２が表示装置３０に押し付けられる力が強く働くので、積層体２が貼着対象物３０に強固に貼着される。 When the second electrode film 22 comes into contact with the spacer 18, the force with which the stacked body 2 is pressed against the display device 30 is stronger than when the second electrode film 22 and the spacer 18 are separated from each other. 2 is firmly attached to the object 30 to be attached.

空気孔１９は積層体２の外周よりも内側であって、スペーサ１８が配置された領域（接続領域）よりは外側に位置しており、押圧は接続領域を挟んで空気孔１９とは反対側の位置から開始されるので、接続領域の貼着が終了した後に空気孔１９が位置する部分が表示装置３０に密着し、貼着される。 The air hole 19 is located on the inner side of the outer periphery of the laminated body 2 and on the outer side of the region (connection region) where the spacer 18 is disposed, and the pressing is opposite to the air hole 19 across the connection region. Therefore, the portion where the air holes 19 are located is in close contact with the display device 30 after the connection region has been attached.

積層体２の空気孔１９が位置する部分が表示装置３０に貼着されると、空気孔１９に連通する貫通孔２８の開口と、その周囲が表示面３５で覆われ、空気孔１９が表示装置３０で塞がれた状態になり、押圧空間３９が外部空間から遮断される。 When the portion of the laminate 2 where the air hole 19 is located is attached to the display device 30, the opening of the through hole 28 communicating with the air hole 19 and its periphery are covered with the display surface 35, and the air hole 19 is displayed. It will be in the state obstruct | occluded with the apparatus 30, and the press space 39 will be interrupted | blocked from external space.

空気孔１９は接続領域と多層体との間に位置するので、空気孔１９が塞がれた後、更に押圧ロール９３を移動させると、積層体２の多層体が位置する部分であって、空気孔１９よりも外側の端部が表示装置３０に貼着され、結果として積層体２の一端から他端まで全て表示装置３０に貼着され、図３に示すようなタッチパネル１が得られる。 Since the air hole 19 is located between the connection region and the multilayer body, after the air hole 19 is blocked, if the pressing roll 93 is further moved, the multilayer body of the laminate 2 is located, The edge part outside the air hole 19 is stuck to the display device 30, and as a result, the laminate 2 is all stuck to the display device 30 from one end to the other end, and the touch panel 1 as shown in FIG. 3 is obtained.

このタッチパネル１では積層体２を表示装置３０に貼付する際に押圧空間３９から余分な空気が押し出されているので、タッチパネル１を第二の基板２０側から押圧して情報を入力するのに必要な動作荷重が０．１Ｎ以上０．３Ｎ以下と小さい。 In this touch panel 1, since extra air is pushed out from the pressing space 39 when the laminate 2 is attached to the display device 30, it is necessary to input information by pressing the touch panel 1 from the second substrate 20 side. Operating load is as small as 0.1N or more and 0.3N or less.

空気孔１９は貼着対象物３０で塞がれるため、タッチパネル１の内部に埃や水分等の汚染原因物質が浸入し難い。また、従来の製造方法では空気孔を塞ぐ工程が別に必要であったのに対し、本発明では空気孔１９は積層体２を貼着対象物に貼り合わせる工程で塞がれるので、従来よりも工程数が少なくてすむ。 Since the air holes 19 are blocked by the object to be adhered 30, it is difficult for contaminants such as dust and moisture to enter the inside of the touch panel 1. In addition, in the conventional manufacturing method, a process for blocking the air holes is separately required, whereas in the present invention, the air holes 19 are blocked in the process of bonding the laminate 2 to the object to be bonded. Fewer steps are required.

以上は、空気孔１９と貫通孔２８を同時に形成する場合について説明したが、本発明はこれに限定されるものではない。空気孔１９と貫通孔２８の形成方法の他の例について説明すると、先ず、第一の基板１０に第二の接着剤２９を貼付する前に、第一の基板１０に空気孔１９を形成しておく（図６（ａ））。 Although the case where the air hole 19 and the through hole 28 are formed simultaneously has been described above, the present invention is not limited to this. To explain another example of the method of forming the air holes 19 and the through holes 28, first, the air holes 19 are formed in the first substrate 10 before the second adhesive 29 is applied to the first substrate 10. (FIG. 6A).

予め所定位置に貫通孔２８が設けられた第二の接着剤２９を用意し、空気孔１９と貫通孔２８が対向するように位置合わせを行った後、第二の接着剤２９を第一の基板１０に貼付すれば、図６（ｂ）に示すように空気孔１９と貫通孔２８とが連通する。 A second adhesive 29 provided with a through hole 28 at a predetermined position is prepared in advance. After alignment is performed so that the air hole 19 and the through hole 28 face each other, the second adhesive 29 is attached to the first adhesive 29. When pasted on the substrate 10, the air hole 19 and the through hole 28 communicate with each other as shown in FIG.

以上は貼着対象物として表示装置３０のように硬く弾性の無いものを用い、積層体２を貼着対象物に押しつけて貼り合わせを行う場合について説明したが本発明はこれに限定されるものではない。図５の符号５は本発明のタッチパネルの他の例を示している。このタッチパネル５では、第一の基板１０は貼着対象物である偏光板３２に貼付され、空気孔１９はその偏光板３２で塞がれている。 Although the above demonstrated the case where the thing which is hard and not elastic like the display apparatus 30 is used as a sticking target object, and the laminated body 2 is pressed on a sticking target object and it bonds, this invention is limited to this. is not. Reference numeral 5 in FIG. 5 shows another example of the touch panel of the present invention. In the touch panel 5, the first substrate 10 is attached to a polarizing plate 32 that is an object to be attached, and the air holes 19 are closed by the polarizing plate 32.

このタッチパネル５を製造する工程の一例を説明すると、先ず、第一、第二の基板１０、２０を貼り合わせて積層体２を形成し、第一の基板１０に第二の接着剤２９を貼付し、第二の接着剤に空気孔１９と連通する貫通孔２８を形成しておく。 An example of a process for manufacturing the touch panel 5 will be described. First, the first and second substrates 10 and 20 are bonded together to form the laminate 2, and the second adhesive 29 is applied to the first substrate 10. A through hole 28 communicating with the air hole 19 is formed in the second adhesive.

この状態の積層体２を上部プレート９５に保持させ、偏光板３２を下部プレート９１の載置面９４に載せ、押圧ロール９３によって偏光板３２の端部を積層体２の空気孔１９とは反対側の端部に押し付けると、偏光板３２の端部が積層体２に貼着される。 The laminated body 2 in this state is held on the upper plate 95, the polarizing plate 32 is placed on the mounting surface 94 of the lower plate 91, and the end of the polarizing plate 32 is opposite to the air holes 19 of the laminated body 2 by the pressing roll 93. When pressed against the end on the side, the end of the polarizing plate 32 is stuck to the laminate 2.

偏光板３２は樹脂フィルムのような弾性体で構成されているので、積層体２に貼着されていない部分は自重により積層体２から離間し、空気孔１９は塞がれておらず、押圧ロール９３が押圧空間３９を通過するときに、押圧空間３９の空気が押し出され、押圧ロール９３が空気孔１９が位置する部分を通過すると、空気孔１９が偏光板３２で塞がれた状態になる。 Since the polarizing plate 32 is made of an elastic body such as a resin film, the portion not attached to the laminate 2 is separated from the laminate 2 by its own weight, and the air holes 19 are not blocked and pressed. When the roll 93 passes through the pressing space 39, the air in the pressing space 39 is pushed out, and when the pressing roll 93 passes through the portion where the air hole 19 is located, the air hole 19 is blocked by the polarizing plate 32. Become.

このタッチパネル５においても、偏光板３２を第一の基板１０に貼り合わせる際に、押圧空間３９の空気が空気孔１９から抜けるので、偏光板３２と第二の接着剤２９との間に空気溜りが生じにくい。 Also in the touch panel 5, when the polarizing plate 32 is bonded to the first substrate 10, the air in the pressing space 39 escapes from the air holes 19, so that air is trapped between the polarizing plate 32 and the second adhesive 29. Is unlikely to occur.

このように本発明の貼着対象物は表示装置に限定されるものではなく、また表示装置２０や偏光板３２以外にも、他のガラス基板等種々のものを用い、積層体２との貼り合わせを行うことができる。 Thus, the sticking object of the present invention is not limited to the display device, and in addition to the display device 20 and the polarizing plate 32, various other materials such as a glass substrate are used, and the sticking to the laminate 2 is performed. Can be combined.

貼着対象物として偏光板３２を用いる場合には、偏光板３２を積層体２に貼付した後に、接着剤３７を介して積層体２を表示装置３０に貼付してもよいが、偏光板３２によって空気孔１９を塞いだ後に積層体２を表示装置３０に貼付すると、表示装置３０と積層体２との間に空気溜りが発生することがあるので、積層体２と表示装置３０との貼り合わせの後に、偏光板３２を貼付することが望ましい。 In the case where the polarizing plate 32 is used as the object to be adhered, the laminated body 2 may be attached to the display device 30 via the adhesive 37 after the polarizing plate 32 is attached to the laminated body 2. If the laminated body 2 is pasted on the display device 30 after the air holes 19 are blocked by the air hole 19, an air pocket may be generated between the display device 30 and the laminated body 2. It is desirable to attach the polarizing plate 32 after the alignment.

しかしながら、表示装置３０は他の部材よりも高価なので、偏光板３２を積層体２に貼付する工程よりも、積層体２を表示装置３０に貼付する工程を先にすると、歩留まりによる損失が大きくなってしまう。従って、積層体２の第一の基板１０側の面に貼付する貼着対象物は偏光板３２よりも表示装置３０であることが好ましい。 However, since the display device 30 is more expensive than other members, the loss due to the yield increases when the step of attaching the laminate 2 to the display device 30 is preceded by the step of attaching the polarizing plate 32 to the laminate 2. End up. Therefore, it is preferable that the object to be attached to the surface of the laminate 2 on the first substrate 10 side is the display device 30 rather than the polarizing plate 32.

以上は、第一の基板１０にスペーサ１８が形成された場合について説明したが、本発明はこれに限定されるものではなく、スペーサ１８は第二の基板２０に設けてもよいし、第一、第二の基板１０、２０の両方に設けてもよい。 The case where the spacer 18 is formed on the first substrate 10 has been described above. However, the present invention is not limited to this, and the spacer 18 may be provided on the second substrate 20. It may be provided on both the second substrates 10 and 20.

また、第一、第二の基板１０、２０のいずれにもスペーサを設けないことも可能であり、この場合は、第一、第二の電極膜１２、２２が直接接触することで互いに電気的に接続される。スペーサを設けない場合には、第一、第二の電極膜１２、２２が接触する領域が接続領域となり、この場合も空気孔１９を接続領域の外側に儲け、その接続領域の空気孔１９とは反対側の位置から空気孔１９に向かって押圧ロール９３を移動させれば、押圧空間３９の空気が押し出され、積層体２が貼着対象物３０に強固に貼着されることになる。 Also, it is possible to provide no spacer on either of the first and second substrates 10 and 20, and in this case, the first and second electrode films 12 and 22 are in direct contact with each other so that they are electrically connected to each other. Connected to. When the spacer is not provided, a region where the first and second electrode films 12 and 22 are in contact with each other serves as a connection region. In this case, the air hole 19 is disposed outside the connection region, If the pressing roll 93 is moved toward the air hole 19 from the opposite side position, the air in the pressing space 39 is pushed out, and the laminate 2 is firmly attached to the attaching object 30.

要するに、本発明は第一、第二の電極膜１２、２２が接続される領域の外側に、押圧空間３９と積層体２の外部空間を接続する空気孔１９を設け、接続領域を挟んで空気孔１９とは反対側の位置から空気孔１９に向かって積層体２を貼着対象物に押圧する位置を移動させ、積層体２と貼着対象物との貼り合わせを行うものである。積層体２の接続領域が位置する部分の貼り合わせが終了した後に空気孔１９が塞がれるのであれば、押圧ロール９３の移動方向も特に限定されるものではない。 In short, in the present invention, the air hole 19 that connects the pressing space 39 and the external space of the laminate 2 is provided outside the region where the first and second electrode films 12 and 22 are connected, and the air is sandwiched between the connection regions. The position where the laminate 2 is pressed against the object to be adhered is moved from the position opposite to the hole 19 toward the air hole 19 to bond the laminate 2 and the object to be adhered. If the air hole 19 is closed after the bonding of the portion where the connection region of the laminate 2 is located, the moving direction of the pressing roll 93 is not particularly limited.

以上は空気孔１９が第一の樹脂フィルム１１と、第一の電極膜１２と、第一の下層絶縁層１３とを貫通する場合について説明したが本発明はこれに限定されるものではなく、空気孔１９は第一の基板１０表面から裏面まで貫通し、表示装置３０に貼付される前の積層体２の押圧空間３９を外部空間と接続するものであれば、例えば、空気孔１９が第一の配線膜１４や第一の上部絶縁層１５を貫通してもよいし、空気孔１９が第一の樹脂フィルム１１だけを貫通していてもよい。 Although the above has described the case where the air holes 19 penetrate the first resin film 11, the first electrode film 12, and the first lower insulating layer 13, the present invention is not limited to this. If the air hole 19 penetrates from the front surface to the back surface of the first substrate 10 and connects the pressing space 39 of the laminate 2 before being attached to the display device 30 to the external space, for example, the air hole 19 is the first one. One wiring film 14 or the first upper insulating layer 15 may be penetrated, or the air hole 19 may penetrate only the first resin film 11.

以上は積層体２に空気孔１９が１つ設けられた場合について説明したが、空気孔１９の数は特に限定されるものではない。空気孔１９を２つ以上設ける場合には、少なくとも１つの空気孔が積層体２の接続領域が貼付された後に塞がるように押圧ロール９３を移動させればよい。 Although the above has described the case where one air hole 19 is provided in the laminate 2, the number of air holes 19 is not particularly limited. When two or more air holes 19 are provided, the pressing roll 93 may be moved so that at least one air hole is closed after the connection region of the laminate 2 is pasted.

以上は、積層体２に第二の接着剤２９を貼付してから、貼着対象物に貼付する場合について説明したが、本発明はこれに限定されるものではない。例えば、積層体２表面に第二の接着剤を配置せず、貼着対象物表面に第二の接着剤を配置してもよいし、積層体２表面と貼着対象物表面の両方に第二の接着剤２９を配置してもよい。貼着対象物表面に第二の接着剤を配置する場合には、第二の接着剤２９に貫通孔を形成する必要がなく、また、第二の接着剤２９はフィルム状であってもよいし、ペースト状であってもよい。 Although the above demonstrated the case where the 2nd adhesive agent 29 was affixed on the laminated body 2, and it affixed on a sticking target object, this invention is not limited to this. For example, the second adhesive may not be disposed on the surface of the laminate 2 and the second adhesive may be disposed on the surface of the object to be adhered, and the second adhesive may be disposed on both the surface of the laminate 2 and the surface of the object to be adhered. Two adhesives 29 may be disposed. When the second adhesive is disposed on the surface of the object to be pasted, it is not necessary to form a through hole in the second adhesive 29, and the second adhesive 29 may be in the form of a film. However, it may be pasty.

以上は第二の接着剤２９を積層体２表面と貼着対象物３０表面のいずれかに配置して貼り合わせを行う場合について説明したが、本発明はこれに限定されるものではなく、例えば、第一の樹脂フィルム１１を熱硬化性樹脂を有する接着フィルムで構成し、第一の樹脂フィルム１１表面を直接貼着対象物に密着させ、加熱押圧すれば、第一の樹脂フィルム１１の接着性によって積層体２が貼着対象物に貼付される。 Although the above demonstrated the case where the 2nd adhesive agent 29 was arrange | positioned and arrange | positioned in either the laminated body 2 surface or the sticking target object 30 surface, this invention is not limited to this, For example, If the 1st resin film 11 is comprised with the adhesive film which has a thermosetting resin, the 1st resin film 11 surface is closely_contact | adhered to a sticking target object, and it heat-presses, adhesion of the 1st resin film 11 will be carried out. The laminate 2 is attached to the object to be attached depending on the property.

この場合は、第一の樹脂フィルム１１を構成する熱硬化性樹脂としては、偏光板特性を損なわない程度の低温で硬化する低温硬化型熱硬化性樹脂を用いることが好ましい。 In this case, as the thermosetting resin constituting the first resin film 11, it is preferable to use a low-temperature curable thermosetting resin that cures at a low temperature that does not impair the polarizing plate characteristics.

以上は第一、第二の電極膜１２、２２が第一、第二の樹脂フィルム１１、２１表面に全面成膜された場合について説明したが、本発明はこれに限定されるものではなく、第一、第二の電極膜１２、２２を所定パターンにパターニングして形成してもよい。第一電極膜１２をパターニングする場合には、空気孔１９を第一の電極膜１２に貫通して形成する必要がなく、第一の樹脂フィルム１１に形成された空気孔１９を避けるように第一の電極膜１２をパターニングしてもよい。 The above has described the case where the first and second electrode films 12 and 22 are formed on the entire surface of the first and second resin films 11 and 21, but the present invention is not limited thereto. The first and second electrode films 12 and 22 may be formed by patterning in a predetermined pattern. When patterning the first electrode film 12, it is not necessary to form the air holes 19 penetrating the first electrode film 12, and the first air film 19 is formed so as to avoid the air holes 19 formed in the first resin film 11. One electrode film 12 may be patterned.

以上は、表示装置３０がＬＣＤで構成された場合について説明したが、本発明はこれに限定されるものではなく、ＣＲＴ（Ｃａｔｈｏｄｅ−ｒａｙｔｕｂｅ）モニター、ＥＬＤ（ＥｌｅｃｔｒｏＬｕｍｉｎｅｓｃｅｎｃｅＤｉｓｐｌａｙ）等、種々の表示装置を用いることもできる。 In the above, the case where the display device 30 is configured by an LCD has been described. However, the present invention is not limited to this, and various displays such as a CRT (Cathode-ray tube) monitor, an ELD (Electro Luminescence Display), etc. An apparatus can also be used.

積層体２を貼着対象物に押し当てる手段も押圧ロールに限定されるものではなく、種々の押圧手段を用いることができる。また、積層体２を貼着対象物に押圧する際に加熱を行う場合には、押圧ロールに加熱手段を内蔵させることもできる。 The means for pressing the laminate 2 against the object to be adhered is not limited to the pressing roll, and various pressing means can be used. Moreover, when heating when pressing the laminated body 2 to a sticking target object, a heating means can also be incorporated in a press roll.

以上は、積層体２を下部プレート９１上に配置し、貼着対象物３０を下部プレート９１上の上部プレート９５に保持させる場合について説明したが、貼り合わせのときの積層体２の向きと貼着対象物３０の向きは特に限定されるものではなく、積層体２を押圧ロールで貼着対象物３０に押し当てるような機械構成であれば、例えば、押圧ロールが設けられた上部プレートに積層体２を保持させ、上部プレート下方の下部プレートに貼着対象物を載置してもよい。 The above has described the case where the laminated body 2 is arranged on the lower plate 91 and the object to be adhered 30 is held on the upper plate 95 on the lower plate 91. However, the orientation and the pasting of the laminated body 2 at the time of bonding are described. The direction of the wearing object 30 is not particularly limited, and for example, if it is a mechanical configuration that presses the laminate 2 against the sticking object 30 with a pressing roll, it is laminated on the upper plate provided with the pressing roll, for example. The body 2 may be held and the object to be adhered may be placed on the lower plate below the upper plate.

しかしながら、積層体２を貼着対象物１０の下方に載置する場合には、積層体２の押圧ロール９３が通過しない部分が自重で貼着対象物から離間した状態となるので、特に保持器具等を用いなくても空気孔１９を貼着対象物３０で塞がずに貼り合わせを行うことができる。 However, in the case where the laminate 2 is placed below the object 10 to be attached, the portion of the laminate 2 through which the pressing roll 93 does not pass is in a state of being separated from the object to be attached by its own weight. Even if it does not use etc., bonding can be performed without obstruct | occluding the air hole 19 with the sticking target object 30. FIG.
