JP-A-9-113906

  However, an actual electro-optical device is manufactured by sealing an electro-optical material from an opening in a space portion and then sealing the opening with a sealing member. Is also overhanging. Due to the presence of the sealing member, there is a certain limit in reducing the width of the extended portion even if only the external connection terminal is provided in the extended portion.

  The present invention has been made in view of the above problems, and an object thereof is to provide an electro-optical device capable of reducing the substrate size and an electronic apparatus including such an electro-optical device.

In order to solve the above problems, an electro-optical device of the present invention includes a pair of substrates that are opposed to each other at a predetermined interval and that one substrate extends from the other substrate at least on one side when viewed in plan, A sealing material for bonding peripheral edges of opposing surfaces of the pair of substrates so as to form an internal space between the pair of substrates and to define an opening leading to the internal space at a predetermined position on the one side; A sealing member that seals the opening; an electro-optic material housed in the internal space; a display electrode provided on the one substrate so as to face the internal space; and the display A circuit portion provided on the one substrate for driving the electrodes, and the other of the extending portions that are electrically connected to a part of the circuit portion and extend on the one side of the one substrate The side facing the substrate A plurality of external connections provided in a region other than a region where the region where the sealing member is disposed is extended in the extending direction of the extending portion between the sealing member and the outer edge of the extending portion The opening and the sealing member are provided in a central portion of the one side, and the plurality of external connection terminals are provided on both sides of the central portion in the one side, respectively. It consists of two terminal groups, and the first and second terminal groups are electrically connected to the two end portions of the wiring board having two end portions with one end bifurcated .

  According to the electro-optical device of the present invention, a pair of substrates in which at least one side extends from the other substrate is opposed to each other at a predetermined interval, and the peripheral edges of the opposed surfaces of both substrates are sealed with a sealing material. The internal space is configured by sealing. An electro-optical material such as liquid crystal is sealed in the internal space. Therefore, the sealing material is disposed so as to define an opening leading to the internal space at a predetermined position on the one side, and the opening is sealed with a sealing member after injecting the electro-optical material into the internal space. Here, the sealing member is not particularly limited, and may be a member applied to any of various sealing methods such as molding and fitting.

  Among the pair of substrates, the substrate extending from the other includes, for example, wiring such as a scanning line and a data line, an electronic element such as a thin film transistor (hereinafter referred to as “TFT” as appropriate), a data line driving circuit, A circuit portion for driving the display electrode is constituted by a scanning line driving circuit or the like, and the display electrode is formed on the upper layer side thereof. The display electrode is disposed facing the internal space in order to operate the electro-optic material.

  In the board, an extension part extending from the other board on one side is provided with an external connection terminal electrically connected to a part of the circuit part. In addition, a part of the sealing member protrudes from a portion facing the opening of the extending portion. In this way, if components that should be provided outside the internal space, such as external connection terminals and sealing members, are arranged in the extending portion, the area that does not face the internal space is minimized. The substrate size can be reduced.

  The extending portion is usually laid out so that the sealing member is arranged at the center of the one side and the external connection terminals are arranged on the outer edge side of the sealing member. That is, the sealing member and the external connection terminal are arranged in the extending direction of the extending portion. On the other hand, in the extension part in the present invention, the external connection terminal is other than the area where the arrangement region of the sealing member is extended in the extension direction of the extension part between the sealing member and the outer edge of the extension part. It is provided in the area. In other words, the plurality of external connection terminals and the sealing member are arranged in different regions in the direction in which the one side extends (that is, the direction intersecting the extending direction of the extending portion), and the extending portion extends. There is no line in the direction.

  By devising the layout in this way, the width of the extending portion in the extending direction can be shortened. Therefore, space saving of the electro-optical device can be realized by reducing the substrate size. In particular, by reducing the substrate size, the number of electro-optical devices manufactured from one wafer can be increased, which has a great effect on reduction in manufacturing cost and improvement in manufacturing efficiency. For example, even if the amount of reduction per sheet is a relatively small amount of about 1 mm, if it is arranged on the same wafer by several to several tens or several hundreds, the same wafer. There may be a case where an electro-optical device can be formed by an extra line or lines. Therefore, it is significantly advantageous in practice.

  Alternatively, if the external connection terminals are arranged in the layout according to the present invention, the space for the sealing member can be expanded. Therefore, when the electro-optical device is downsized, a space for the sealing member can be relatively secured to some extent, and a small electro-optical device that can be easily manufactured can be realized.

In the present invention, in particular, the plurality of external connection terminals include first and second terminal groups provided on both sides of the central portion on the one side , and the first and second terminal groups are bifurcated at one end. branched in the wiring substrate having two ends that are connected to respective electrically said two end portions formed by.

Therefore, since the two terminal groups are commonly connected to the bifurcated wiring board, the number of members can be reduced, which is advantageous in terms of cost.

  In another aspect of the electro-optical device according to the aspect of the invention, the circuit unit is partially electrically connected to a terminal that supplies an image signal among the plurality of external connection terminals, and at least the other part is the one of the ones. A driving circuit provided in a region of the substrate facing the other substrate and driven by the supply of the image signal;

  According to this aspect, all or a part of the driving circuit (so-called data line driving circuit) driven by receiving the image signal from the external connection terminal is located in a region of the extending substrate facing the other substrate. Is provided.

  In general, the data line driving circuit is provided so as to extend along the one side, and is connected to a large number of external connection terminals at both ends via wiring for inputting an image signal. Therefore, since a space for routing a large number of wirings around the periphery is required, the drive circuit is often provided in an extended portion with few spatial restrictions together with the external connection terminals. In this case, however, the width of the extending portion is expanded according to the size and shape of the drive circuit.

  On the other hand, in this embodiment, at least the part other than the part electrically connected to the external connection terminal for supplying the image signal is removed from the extending part in the data line driving circuit. The width of the extending portion is shortened, and the electro-optical device can be further reduced in space or reduced in size.

  In an aspect in which the driving circuit is provided in a region of the one substrate facing the other substrate, the driving circuit may be provided at least partially in the region where the sealing material is disposed on the one substrate. .

  In this case, all or part of the drive circuit is provided in a region where the sealing material is disposed in a region where the pair of substrates are opposed to each other. That is, the portion of the drive circuit that is provided in the same region as the sealing material is present between the region facing the internal space and the extending portion of the one substrate. Accordingly, the space for the driving circuit can be omitted from the substrate, and the width of the extending portion can be further shortened.

  Alternatively, the drive circuit may be provided at least partially in a region facing the internal space on the one substrate.

  In this case, a part or front part of the circuit part is provided in a region facing the internal space. The sealing material is originally required to define the internal space. From the viewpoint of space saving, it is preferable that the region where the sealing material is disposed is narrow. Therefore, if the extension part cannot fit in the arrangement area of the sealing material or if an empty space can be secured in the area facing the internal space, the extension can be achieved by shifting the drive circuit space to the area facing the internal space. It is possible to further reduce the width of the existing portion.

  In order to solve the above problems, an electronic apparatus according to the present invention includes the above-described electro-optical device according to the present invention (including various aspects thereof).

  According to the electronic apparatus of the present invention, since the electro-optical device of the present invention described above is provided, a space-saving or miniaturized projection display device, liquid crystal television, mobile phone, electronic notebook, word processor, viewfinder type, or Various electronic devices such as a monitor direct-view video tape recorder, a workstation, a videophone, a POS terminal, and a touch panel can be realized. Further, as the electronic apparatus of the present invention, for example, an electrophoresis apparatus such as electronic paper can be realized.

  Such an operation and other advantages of the present invention will become apparent from the embodiments described below.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<1: Embodiment of electro-optical device>
With reference to FIGS. 1 to 10, an embodiment of the electro-optical device of the invention will be described. In the following embodiments, the electro-optical device of the present invention is applied to a liquid crystal device.

<1-1: First Embodiment>
First, a liquid crystal device according to a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a plan view showing the configuration of the liquid crystal device according to the present embodiment, and FIG. 2 shows a cross section taken along line II ′ of FIG. FIG. 3 shows a comparative example of the liquid crystal device according to this embodiment. FIG. 4 shows the configuration of a mounting case that houses the liquid crystal device according to the present embodiment.

  In FIG. 1 and FIG. 2, in the liquid crystal device 100, the opposing substrate 20 is opposed to the TFT array substrate 10 at a predetermined interval, and the peripheral edges of the opposing surfaces of both substrates are bonded together with a sealing material 52a to form an internal space. Has been. The TFT array substrate 10 has an extending portion 201 extending from the counter substrate 20 in plan view, and the sealing material 52a is formed at a predetermined location on the side where the extending portion 201 extends (here, this side). The opening leading to the internal space is defined with respect to both ends. The liquid crystal layer 50 is constituted by the liquid crystal injected from the opening into the internal space, and the openings are sealed with the sealing mold materials 151a and 151b, respectively. The frame light shielding film 53 provided along the inner edge of the sealing material 52a defines an image display area 10a in which an image is displayed.

  The liquid crystal device 100 is a built-in drive circuit type, and adopts a TFT active matrix drive system. Therefore, in the opposing surface (upper surface in FIG. 2) of the TFT array substrate 10, the “display electrode” of the present invention is provided in the image display region 10 a on the upper layer of the pixel switching TFT, the scanning line, the data line and the like. As an example, a pixel electrode 9a is provided. An alignment film 16 is formed immediately above the pixel electrode 9a. A counter electrode 21 is formed on a counter surface (the lower surface in FIG. 2) of the counter substrate 20 via a stripe-shaped light shielding film 23, and an alignment film 22 is formed thereon. Further, at least one corner (all four in this case) of the counter substrate 20 is provided with a vertical conduction terminal 106 that is electrically connected to the TFT array substrate 10. The alignment state of the liquid crystal in the liquid crystal layer 50 changes according to the electric field applied between the pixel electrode 9a and the counter electrode 21, but is defined by the alignment film 16 and the alignment film 22 when no electric field is applied. The initial orientation is taken.

  A scanning line driving circuit 104 and a wiring 105 for driving a scanning line are provided in a region where the frame light shielding film 53 is formed on the opposing surface of the TFT array substrate 10. In FIG. 1, one scanning line driving circuit 104 is provided on each of the left and right sides of the frame light-shielding film 53, and a wiring 105 is connected to the two light-shielding film circuits 104 to connect the two scanning line driving circuits 104 to each other. It is drawn to the upper side.

  In the extended portion 201 of the TFT array substrate 10, as a specific example of the “drive circuit” of the present invention, a data line drive circuit 101a for driving a data line is arranged along the lower side of the seal material 52a in FIG. Has been. However, the upper half of the data line driving circuit 101a is provided so as to overlap the sealing material 52a in plan view. In addition, in the lower half, portions protruding from the openings of the sealing mold materials 151a and 151b are overlapped with both ends.

  In the present embodiment, electronic elements such as TFTs, wiring lines such as scanning lines and data lines, circuits on the TFT array substrate 10 including the scanning line driving circuit 104 and the data line driving circuit 101a are all included in the present invention. This corresponds to a specific example of “circuit unit”. In addition to the data line driving circuit 101, the extending portion 201 includes a sampling circuit that applies image signals to a plurality of data lines at a predetermined timing, and a precharge signal having a predetermined voltage level applied to the plurality of data lines. In addition, a precharge circuit to be supplied in advance of each other, an inspection circuit for inspecting quality, defects, and the like of the liquid crystal device 100 during manufacture or at the time of shipment may be formed.

  Furthermore, in the present embodiment, a large number of external connection terminals 102a are provided in a region Rc between the region Ra on the outer edge side of the sealing mold material 151a in the extending portion 201 and the region Rb on the outer edge side of the sealing mold material 151b. Is provided. Here, the regions Ra and Rb are specific examples of the “region in which the arrangement region of the sealing member is extended in the extending direction of the extending portion between the sealing member and the outer edge of the extending portion” in the present invention. It corresponds to. The “extending direction” of the extending part 201 is the direction of the arrow Y shown in FIG.

  These external connection terminals 102a are provided to supply power and signals from the external circuit connected via the FPC 110 to the liquid crystal device 100. In the liquid crystal device 100, scanning line driving is performed via the wiring 103a. The driving circuit such as the circuit 104 or the data line driving circuit 101a is appropriately connected. In the liquid crystal device 100, the pixel electrode 9a is driven according to the supplied signal, and an image is displayed. Here, the data line driving circuit 101a is connected to the plurality of external connection terminals 102a via the wiring 103a at both ends on the extending portion 201 side.

  As shown in FIG. 3, in the liquid crystal device according to the comparative example of the present embodiment, the region Ra ′ where the sealing mold material 150 is disposed and the region Rc ′ where the external connection terminal 102 is disposed extend. The portions 200 overlap each other in the extending direction. Since the external connection terminal 102 must be connected to the FPC 110, it is necessary to be separated from the sealing mold material 150 to some extent in order to prevent the sealing molding material 150 from overlapping on the external connection terminal 102. As a result, the extending portion 200 has a predetermined width L0, and a space sufficient to arrange the entire data line driving circuit 101 is generated.

  On the other hand, in the liquid crystal device 100 of the present embodiment, as described above, the external connection terminal 102a and the sealing mold materials 151a and 151b are arranged in different regions in the extending direction of the extending portion 201. Therefore, the external connection terminal 102a does not need to be spaced from the sealing mold materials 151a and 151b. Further, in FIG. 1, by providing the upper half of the data line driving circuit 101a in the region where the sealing material 52a is disposed, the position of the external connection terminal 102a can be pushed upward. As a result, the width L11 of the extending part 201 can be shorter than the width L0 of the extending part 200 in the comparative example.

  Therefore, the liquid crystal device 100 according to the present embodiment can save space, and a high degree of design freedom can be given to an electronic device to which the liquid crystal device 100 is applied. In addition, the number of liquid crystal devices manufactured from one wafer can be increased, and a great effect is exhibited for improving the manufacturing efficiency and reducing the manufacturing cost. That is, even if the reduction width of the extension portion 201 in one liquid crystal device 100 is small, a region corresponding to the TFT array substrate 10 is usually formed on the wafer in units of hundreds to thousands. Further, since a large number of such wafers are produced, it is extremely effective in manufacturing.

  Further, here, on the lower side of the sealing material 52a or the counter substrate 20 in FIG. 1, the opening and the sealing molding materials 150a and 150b are arranged at both ends, and the external connection terminal 102a is arranged at the center. Therefore, even if the wiring 103a is routed separately from the center to the left and right, the wiring length can be made substantially equal on the left and right, so that problems such as signal delay on the left and right do not occur. In addition, since the openings are defined at the left and right ends, the liquid crystal can be efficiently and uniformly injected into the internal space.

  In FIG. 4, in the mounting case 300 that accommodates the liquid crystal device 100, the FPC 110 is pulled out from the opening 301 provided in the center of the side on the extending portion 201 side, so that fixing members such as screws are arranged at both ends. The hole 302 to be provided can be formed. That is, the liquid crystal device 100 according to the present embodiment can be fixed at a fixed point that is symmetrical in plan view by the mounting case 300 by arranging the external connection terminal 102a in the center. Further, if the hole portions 302 are provided at both ends of the side opposite to the side where the opening 301 is provided, the mounting case can be fixed at four points at the positions of the apexes of the quadrilateral as viewed in a plan view. Therefore, in addition to the above operations and effects, the liquid crystal device 100 can be stably attached without being displaced.

<1-2: Modification>
Next, a liquid crystal device according to a modification of the first embodiment will be described with reference to FIGS. 5 to 8 respectively show the configuration of the liquid crystal device according to a modification of the first embodiment.

<1-2-1: First Modification>
The liquid crystal device 100 can be variously modified. For example, in the liquid crystal device 100, the openings and the sealing mold materials 150a and 150b are arranged at both ends on the lower side of the sealing material 52a or the counter substrate 20 in FIG. Further, a sealing mold material may be provided. In the first modification shown in FIG. 5, the sealing material 52aa is arranged so as to define only the opening on the left end side on the lower side of the counter substrate 20, and this is sealed by the sealing mold material 150a. Even in this case, the width L12 of the extending portion 201a can be shortened as compared with the normal case as in the comparative example.

<1-2-2: Second Modification>
Further, in the liquid crystal device 100, the sealing mold materials 150a and 150b and the external connection terminal 102a are both arranged symmetrically, but in the second modification shown in FIG. In this case, an opening defined by the sealing material 52ab and a sealing mold material 152 are arranged, and an external connection terminal 102b is arranged on the right side. Even when the sealing mold material and the external connection terminal are arranged asymmetrically with respect to the lower side of the counter substrate 20 as described above, the sealing mold material and the external connection terminals are arranged in different regions in the extending direction of the extending portion. In other words, the width L13 of the extending portion 201b can be shortened as compared with the normal case as in the comparative example.

<1-2-3: Third Modification>
Further, in the liquid crystal device 100, the data line driving circuit 101a is provided in a region straddling the region where the sealing material 52a is disposed and the extending portion 201. However, by moving the data line driving circuit further upward, The degree of integration between the connection terminal and the sealing mold material can be increased, and the width of the extending portion can be further reduced.

  In the third modification shown in FIG. 7, the data line driving circuit 101 b includes a region where the sealing material 52 a is disposed from a region facing the internal space of the TFT array substrate 10 (that is, a region inside the sealing material 52 a). It is provided over the extending part 201c. In this case, it is possible to easily reduce the space in the extending portion 201c while taking a sufficient space for arranging the data line driving circuit 101b on the TFT array substrate 10. Therefore, if the degree of integration between the external connection terminals 102aa and the sealing mold materials 151a and 151b is increased, the width L14 of the extending portion 201c can be further shortened, and a further effect can be achieved in reducing the manufacturing cost.

<1-2-4: Fourth Modification>
Alternatively, in the fourth modified example shown in FIG. 8, the data line driving circuit 101c is provided across the area inside the sealing material 52a and the area where the sealing material 52a is disposed. In this case, since the data line driving circuit 101c is removed from the extending portion 201d, if the degree of integration between the external connection terminal 102ab and the sealing mold materials 151a and 151b is further increased, the width L15 of the extending portion 201d is greatly increased. Shortened to Therefore, it is possible to further improve the manufacturing cost reduction.

  Also in the modified examples as described above, it is possible to save the space of the liquid crystal device by shortening the width of the extending portion, and a great effect is exhibited for improving the manufacturing efficiency and reducing the manufacturing cost. When the size of the data line driving circuit itself can be reduced or when a sufficient space can be provided inside the sealing material 52a, the entire data line driving circuit may be provided inside the sealing material 52a. Good.

<1-3: Second Embodiment>
Next, a liquid crystal device according to a second embodiment will be described with reference to FIG. FIG. 9 shows the configuration of the liquid crystal device according to this embodiment. Note that the liquid crystal device 100A of the present embodiment is configured in the same manner as the liquid crystal device 100 except that the layout in the extending portion is different. The description is omitted as appropriate.

  In FIG. 9, in the liquid crystal device 100 </ b> A, the sealing material 52 b is disposed so as to define one opening at the center of the lower side of the counter substrate 20, and the opening is sealed with the sealing mold material 153. A large number of external connection terminals 102c and 102d are provided in the regions R2 and R3 on both sides of the region R1 on the outer edge side with respect to the sealing mold material 153 in the extending portion 202, respectively.

  Thus, also in this embodiment, since the sealing mold material 153 and the external connection terminals 102c and 102d are arranged in different regions in the extending direction of the extending portion 202, the width L21 of the extending portion 202 is This can be shortened compared to the normal case as in the comparative example. Therefore, even with such a configuration, it is possible to save the space of the liquid crystal device, and a great effect is exhibited for improving manufacturing efficiency and reducing manufacturing cost.

  Further, since the external connection terminals are arranged separately in the left and right regions R2 and R3, the length of the lead-out wiring 103b connected to the external connection terminals 102c and 102d is shortened. Since the external connection terminals 102c and 102d are symmetrically arranged, there is almost no difference in wiring length.

  Further, here, the FPC 111a is connected to the external connection terminal 102c, and the FPC 111b is connected to the external connection terminal 102d. By connecting the external connection terminal 102c and the external connection terminal 102d to the independent FPCs 111a and 111b in this way, for example, an increase in the wiring length on the FPC side can be suppressed as compared with the case of connecting to a bifurcated FPC. Can be made less susceptible to signal delays and noise.

  Further, in the second embodiment, two independent FPCs 111a and 111b are connected to the external connection terminals 102c and 102d. In addition to this, for example, as shown in FIG. The FPC 112 may be used. In this case, since the external connection terminals 102c and 102d are commonly connected to the FPC 112, the number of members can be reduced, which is advantageous in terms of cost.

  It should be noted that the second embodiment described above can be modified in the same manner as various modifications to the first embodiment.

<2: Electronic equipment>

  In FIG. 11, a projector 1100 includes a lamp unit 1102 made of a white light source such as a halogen lamp. The projection light emitted from the lamp unit 1102 is separated into three primary colors of RGB by four mirrors 1106 and two dichroic mirrors 1108 arranged in the light guide, and liquid crystal as a light valve corresponding to each primary color. It is incident on the devices 100R, 100B and 100G. The configurations of the liquid crystal devices 100R, 100B, and 100G are the same as those of the liquid crystal device described above, and R, G, and B primary color signals supplied from the image signal processing circuit are modulated in each. Light modulated by the liquid crystal devices 100R, 100B, and 100G enters the dichroic prism 1112 from three directions. As a result, the images of the respective colors are combined, and a color image is projected onto the screen 1120 and the like via the projection lens 1114.

  In addition to the liquid crystal device described above, the electro-optical device of the present invention includes, for example, an organic EL device, an electrophoretic device such as electronic paper, and a display device using an electron emitting element (Field Emission Display and Surface-Conduction Electron-Emitter Display). ) And the like.
