Description

  The present invention relates to a method of forming a composite pattern having a combination portion formed by combining repetition of fine patterns such as a color filter used in a liquid crystal display device, and the forming apparatus.

  Conventionally, a photolithographic method using a photoresist material has been adopted for manufacturing a color filter for a liquid crystal display device, but most of the photoresist material as a pixel material is discarded at the time of spin coating, There is a problem that this photoresist material cannot be used economically. In addition, the overall work efficiency is low because the process of exposure and development is performed for each color, and expensive optical equipment such as an exposure apparatus and a development apparatus is required, which makes it impossible to reduce the cost. There is also a problem.

Therefore, in recent years, there are attempts to obtain this color filter by printing. For example, when obtaining a pattern with four pattern constituent colors of black (black matrix), red, green, and blue, an intaglio or lithographic printing plate is prepared for each pattern constituent color, and the pattern constituent is prepared from the plate. A colored resin composition (for example, color ink) is transferred to each color roller to transfer the pattern to each roller, and the black (black matrix) pattern position is used as a reference, and then red, then green, blue And a method of transferring each pattern constituent color to the substrate.
In addition, a removal plate that is a relief plate is prepared for each pattern constituent color pattern, and a colored resin composition of the pattern constituent color is applied to a roller for each pattern constituent color at a constant thickness, and this roller corresponds to the pattern constituent color. By pressing the removal plate and transferring and removing excess colored resin composition other than the pattern at the convex portion of the removal plate, a pattern is formed on the roller for each pattern constituent color, and these patterns are the same as described above. A device for obtaining a pattern as a color filter by transferring the pattern pattern color to the substrate so that each of the red, green, and blue colors does not overlap each other with the position of the black pattern as a reference is proposed. (For example, see Patent Document 1)
JP 11-058921 A (paragraph number 0008, FIG. 1)

The manufacturing of the color filter by printing described above does not require an exposure apparatus or a developing apparatus as compared with the photolithography method, and therefore it is easy to reduce the manufacturing cost. In addition, there is an advantage that the thickness of the color material of the pattern is simple.
However, in the pattern forming apparatus using the printing method described above, a plate-shaped removal plate (projection plate) having a desired pattern is created for each pattern constituent color, and these are arranged side by side in the moving direction of a plurality of rollers. In the present situation where there is a disadvantage that the forming apparatus is increased in size, and in particular, there is a tendency to increase the size of the color filter, when the pattern forming apparatus using the printing method is used, the longitudinal dimension of the apparatus is required. Will be very long.
This problem occurs not only in the case of a color filter for a liquid crystal display device, but also when a composite pattern having pattern combination portions having different pattern constituent colors is formed by printing.
Therefore, in view of the above circumstances, the present invention aims to reduce the number of removal plates for forming a plurality of patterns having different pattern constituent colors on the application roller, and to reduce the number of the removal plates. An object of the present invention is to obtain a good composite pattern by easily transferring the pattern formed on each roller with respect to the reference on the substrate.

(Coating solution removal unit)
In the coating liquid removing unit 4, a first coating liquid removing plate 41 and a second coating liquid removing plate 42 are arranged on the circumferential surface of the body 40 so as to be aligned in the body rotation direction. The coating liquid removing unit 4 serves as a coating liquid supply unit, a coating roller 2BM to which black ink is applied at a constant thickness from the constant thickness coating liquid supply units 3BM, 3R, 3G, and 3B in the coating liquid supply unit 3. Application roller moving mechanism unit 2 in which application roller 2R applied with a constant thickness of red ink, application roller 2G applied with a constant thickness of green ink, and application roller 2B applied with a constant thickness of blue ink are integrated. Moves in the printing direction (left direction in the figure) and corresponds to the plates 42, 41R, 41G, 41B arranged on the peripheral surface of the rotating body 40, respectively, and the rotating application rollers 2BM, 2R, 2G, 2B. The excess coating liquid is transferred and removed from the blankets 6BM, 6R, 6G, and 6B of the coating rollers 2BM, 2R, 2G, and 2B.

First, the first coating liquid removal plate 41 is provided on the peripheral surface of the body 40 with a convex portion a having negative patterns of patterns Pr, Pg, and Pb having the same shape constituting the combination portion P1. Plate 41R, 41G, 41B. Then, the blanket 6R of the application roller 2R to which the red application liquid is applied and supplied is pressed against the plate 41R of the first application liquid removal plate 4, and the blanket 6R is rotated by the rotation of the body 40 and the application roller 2R. The excess coating solution is transferred and removed from the projection 41a of the plate 41R so that the coating solution remaining on the blanket 6R becomes the pattern Pr. Further, the blanket 6G of the application roller 2G to which the green application liquid is applied and supplied is pressed against the plate 41G of the first application liquid removal plate 4, and the blanket 6G is rotated by the rotation of the body 40 and the rotation of the application roller 2G. The excess coating solution is transferred and removed from the projection 41a of the plate 41G so that the coating solution remaining on the blanket 6G becomes a pattern Pg. Further, the blanket 6B of the application roller 2B to which the blue application liquid is applied and supplied is pressed against the plate 41B of the first application liquid removal plate 4, and the blanket 6B is rotated by rotation of the body 40 and rotation of the application roller 2B. The excess coating liquid is transferred and removed from the convex portion a of the plate 41B so that the coating liquid remaining on the blanket 6B becomes a pattern Pb.
The second coating liquid removal plate 42 is a plate that is provided on the peripheral surface of the body 40 with a convex portion a as a negative pattern of the pattern P2 other than the combination portion. Then, the blanket 6BM of the application roller 2BM supplied with the black application liquid is pressed against the second application liquid removal plate 42, and the body 40 and the application roller 2BM rotate to rotate the blanket 6BM. The coating liquid is transferred and removed to the convex part a of the second coating liquid removal plate 42 so that the coating liquid remaining on the blanket 6BM becomes a pattern P2. Thereby, with the rotation of the body 40, the residual coating liquid can be removed by the cleaning means in the tank.
The convex portion a may have the same shape or different shape for each color.
The coating solution removing unit 4 has the lower side of the body 40 positioned in the tank-like residual coating solution removing device 7. Further, the coating solution removing unit 4 and the remaining coating solution removing device 7 are supported by the position adjusting means 8, and the coating solution removing unit 4 and the remaining coating solution removing device 7 are moved together. It is provided as possible.

(Positioning, ink transfer removal-coating roller 2BM)
In the illustrated embodiment, the moving direction of the application roller moving mechanism unit 2 is aligned with the longitudinal direction of the stripe formed by the convex portion a. Then, the application roller moving mechanism unit 2 starts to move toward the substrate support unit 5 as the printing direction, and before the application roller 2BM is pressed against the second application liquid removal plate 42 of the application liquid removal unit 4, this application is performed. A portion of the roller 2BM where the coating liquid is transferred and removed, that is, a pattern P2 made of black ink formed on the coating roller 2BM (a pattern corresponding to the position of the pattern P2 made of black ink set on the substrate support portion 5 side). The second coating liquid removal plate 42 is aligned by the position adjusting means 8 so that the convex portion a of the second coating liquid removal plate 42 corresponds to the negative pattern.
When the positioning is completed before pressing by the application roller 2BM and the application roller 2BM comes into contact with the peripheral surface of the body 40 in this state, the movement of the application roller moving mechanism unit 2 is temporarily stopped, and the application roller Both the 2BM and the body 40 rotate in a synchronized state, the blanket 6BM of the coating roller 2BM presses the second coating liquid removal plate 42, and the convex portion a of the second coating liquid removal plate 42 causes the blanket 6BM. Then, the excess black ink is transferred and removed, whereby a pattern P2 made of black ink is formed on the coating roll 2BM.
When the transfer removal process for black ink, in which the pattern P2 is formed by the application roller 2BM by the alignment of the second coating liquid removal plate 42 and the transfer removal of the black ink, the application roller moving mechanism unit 2 moves again. The movement of the application roller moving mechanism unit 2 is continued until the application roller 2R and the first application liquid removal plate 41 correspond to each other in a non-contact state. The second coating liquid removal plate 42 moves to a portion where the black ink transferred to the convex portion a of the second coating liquid removal plate 42 is removed by the rotation of the body 40. This point will be described later.

(Positioning, ink transfer removal-coating roller 2R)
As in the case of the application roller 2BM described above, the application liquid of the application roller 2R is transferred before the application roller 2R presses the plate 41R of the first application liquid removal plate 41 of the application liquid removal unit 4 next. The plate 41R is applied to the negative pattern of the portion to be removed, that is, the pattern Pr of red ink formed on the coating roller 2R (the pattern corresponding to the position of the pattern Pr of red ink set on the substrate support portion 5 side). The plate 41R is aligned by the position adjusting means 8 so that the convex portion a of the corresponding position is located.
This positioning is completed before pressing by the application roller 2R, and when the application roller 2R comes into contact with the peripheral surface of the body 40 in this state, the movement of the application roller moving mechanism unit 2 is temporarily stopped, and the application roller 2R And the body 40 rotate in a synchronized state, the blanket 6R of the coating roller 2R presses the plate 41R of the first coating liquid removal plate 41, and the convex portion a of the plate 41R is an excess portion from the blanket 6R. The red ink is transferred and removed, whereby a pattern Pr of red ink is formed on the coating roll 2R.
When the transfer removal process in red ink, in which the pattern Pr is formed by the application roller 2R by aligning the plate 41R of the first coating liquid removal plate 41 and transferring and removing the red ink, the coating roller moving mechanism unit 2 The coating roller moving mechanism 2 is moved again until the coating roller 2G and the plate 41G of the first coating liquid removal plate 41 correspond to each other in a non-contact state. The plate 41R also moves to a portion where the red ink transferred to the convex portion a of the plate 41R is removed by the rotation of the body 40.

(Positioning, ink transfer removal-coating roller 2G)
The same applies to the application roller 2G, and a pattern of green ink formed on the application roller 2G before the application roller 2G presses the plate 41G of the first application liquid removal plate 41 of the application liquid removal unit 4. The plate 41G is aligned by the position adjusting means 8 so that the convex portion a of the plate 41G corresponds to the Pg negative pattern.
This positioning is finished before pressing by the application roller 2G, and when the application roller 2G comes into contact with the peripheral surface of the body 40 in this state, the movement of the application roller moving mechanism unit 2 is temporarily stopped, and the application roller 2G And the body 40 rotate in a synchronized state, the blanket 6G of the coating roller 2G presses the plate 41G, and the convex portion a of the plate 41G transfers and removes excess green ink from the blanket 6G. As a result, a pattern Pg of green ink is formed on the application roller 2G.
When the transfer removal process in green ink, in which the pattern Pg is formed by the application roller 2G by aligning the plate 41G and transferring and removing the green ink, the application roller moving mechanism unit 2 moves again, and this application roller moving mechanism The movement of the part 2 is continued until the time when the coating roller 2B and the plate 41B of the first coating liquid removing plate 41 correspond in a non-contact state. The movement of the plate 41G after the transfer removal is the same as described above, and this plate 41G moves to a portion where the green ink transferred to the convex portion a of the plate 41G is removed by the rotation of the body 40.

(Positioning, ink transfer removal-coating roller 2B)
The alignment with the application roller 2B and the ink transfer removal are the same. Before the application roller 2B presses against the plate 41B of the first application liquid removal plate 41 of the application liquid removal unit 4, the application roller 2B is moved over the application roller 2B. The plate 41B is aligned by the position adjusting means 8 so that the convex portion a of the plate 41B corresponds to the negative pattern Pb of the blue ink to be formed.
This positioning is finished before pressing by the application roller 2B, and when the application roller 2B comes into contact with the peripheral surface of the body 40 in this state, the movement of the application roller moving mechanism 2 is temporarily stopped, and the application roller 2B And the body 40 rotate in a synchronized state, the blanket 6B of the coating roller 2B presses the plate 41B, and the convex portion a of the plate 41B transfers and removes the excess blue ink from the blanket 6B. As a result, a pattern Pb of blue ink is formed on the application roller 2B.
When the transfer removal process in blue ink, in which the pattern Pb is formed by the application roller 2B by aligning the plate 41B and transferring and removing the blue ink, the application roller moving mechanism portion 2 moves to the substrate support portion 5 side. . The movement of the plate 41G after the transfer removal is the same as described above, and this plate 41G moves to a portion where the green ink transferred to the convex portion a of the plate 41G is removed by the rotation of the body 40.

  Since the application roller moving mechanism 2 combined so that the application rollers 2BM, 2R, 2G, and 2B are integrated has a certain length along the moving direction, the application roller is applied as described above. The roller 2BM, 2R, 2G, and 2B are sequentially aligned and removed, and are provided so as to reach the substrate support unit 5 in order from the application roller 2BM that has completed the transfer removal. Before the transfer removal of the application roller is completed, the next process (transfer process) is started from the application roller after the transfer removal. Of course, it is also possible to shift to the next process after completing the transfer removal of all the application rollers without overlapping the processes.

(Residual coating solution removal)
In the coating liquid removing unit 4, the second coating liquid removing plate 42 and the first coating liquid removing plate 41 are portions for removing the coating liquid by rotating the body 40 each time the coating liquid is sequentially transferred and removed. The residual coating liquid removing device 7 is reached.
As shown in FIG. 6, the remaining coating liquid removing apparatus 7 immerses the lower end side of the rotating body 40 and forms a pattern on the blanket side to thereby form second and first coating liquid removing plates 42, 41 (41R, 41G, 41B), the cleaning means 9 made of a solvent stored so as to dissolve the coating liquid remaining on the convex portion a, and the liquid of the cleaning means 9 by the rotation of the body 40 The drying means 10 is located at a position opposite to the convex portion a appearing from the surface and causes the solvent to volatilize by blowing air. For example, taking the second coating liquid removal plate 42 from which black ink is transferred and removed with a negative pattern as an example, the second coating liquid removal plate 42 is immersed in the cleaning means 9 and transferred to the convex portion a. The black ink is dissolved and removed, and the drying means 10 dries the second coating liquid removal plate 42 appearing from the cleaning means 9.
In this way, the second coating liquid removing plate 42 from which the black ink is transferred and removed, the plate 41R of the first coating liquid removing plate 41 from which the red ink is transferred and removed, the plate 41G from which the green ink is transferred and removed, and the blue ink are transferred and removed. The remaining plate 41B sequentially enters the remaining coating solution removing device 7, and the remaining coating solution removing device 7 is provided with a clean plate surface.
The removal by the remaining coating liquid removing device does not require waiting for the completion of the transfer removal by the application rollers 2BM, 2R, 2G, and 2B. For example, when the transfer removal by the application roller 2R is performed In addition, the remaining coating solution is removed and dried on the second coating solution removing plate 42 that has been transferred and removed by the coating roller 2BM.

(Transfer process)
The substrate support portion 5 is formed by attaching and positioning a substrate 50 such as a glass plate as a base material of a color filter on an XYθ driveable surface plate 51. As described above, the application roller moving mechanism 2 is provided so as to move in the printing direction (left direction in the drawing), and the application roller 2BM having the pattern P2 formed on the peripheral surface first reaches the substrate. The pattern P2 is transferred from the blanket 6BM to the surface of the substrate 50 by rolling while pressing the surface of the substrate 50. When the pattern P2 is transferred, the coating roller 2R subsequently presses the surface of the substrate 50, and the pattern Pr formed on the peripheral surface is transferred from the blanket 6R to the surface of the substrate 50 while rolling (FIG. 3). reference). When the pattern Pr is transferred, the coating roller 2G subsequently presses the surface of the substrate 50, and the pattern Pg formed on the peripheral surface is transferred from the blanket 6G to the surface of the substrate 50 while rolling. Further, when the pattern Pg is transferred, the coating roller 2B subsequently presses the surface of the substrate 50, and the pattern Pb formed on the peripheral surface is transferred from the blanket 6B to the surface of the substrate 50 while rolling.
In the transfer process, the transfer of the pattern P2 from the first application roller 2BM is started at the end of the transfer removal at the application roller 2B located at the end of the application roller moving mechanism 2 or the first application liquid removal plate 41. There is no need to wait for the cleaning of the plate 41B to finish, and the transfer process of the black ink coating liquid and the transfer removal process of the green ink coating liquid can be overlapped.
In this way, as the coating roller moving mechanism 2 moves in the printing direction, the patterns P2, Pr, Pg, and Pb are sequentially transferred from the coating rollers 2BM, 2R, 2G, and 2B to the surface of the substrate 50, and are thus printed with black ink. A composite pattern P composed of the pattern P2 and the patterns Pr, Pg, and Pb in the combination portion P1 of red ink, green ink, and blue ink is formed. Each pattern Pr, Pg, and Pb may partially overlap P2. Further, the patterns Pr, Pg, and Pb may be partially stacked on each other.

  In the transfer step, the circumferential directions of the application rollers 2BM, 2R, 2G, and 2B are set so that the patterns P2, Pr, Pg, and Pb in the printing movement direction of the substrate support 5 are aligned. The pattern position is adjusted at the time of forming each pattern P2, Pr, Pg, Pb, and by the rotation of each coating roller 2BM, 2R, 2G, 2B in the transfer process. In addition, the blanket of the coating roller that comes later in the transfer order of the pattern to the substrate 50 comes into contact with the pattern previously transferred to the substrate 50, but the substrate 50 side is provided with a high strength to hold the coating liquid. Therefore, the coating liquid does not retransfer from the substrate 50 to the blanket of the rear coating roller. As one method for making the strength (adhesive strength) for holding the coating solution on the substrate 50 side larger than the peel strength between the blanket and the coating solution, a transparent adhesive on the surface of the substrate 50 is used. It is possible to provide a layer.

  When the transfer from the rear application roller 2B of the application roller moving mechanism unit 2 is completed as described above, the application roller moving mechanism unit 2 avoids contact with the application liquid removing unit 4 and the substrate support unit 5. Returning to the standby position, ink is applied and supplied from the application liquid supply unit 3 to each application roller. When the coating roller moving mechanism 2 is in the standby position, the substrate 50 is replaced. When the replacement of the substrate 50 and the ink supply are completed, the coating roller moving mechanism 2 starts moving in the printing direction again. The above-described pattern formation and transfer to the substrate are performed.

The first examination technique includes coating rollers 2BM, 2R, 2G, and 2B to which coating liquids having different pattern constituent colors are supplied, and a coating liquid removing plate (first coating liquid removing plate) for each pattern constituent color. 41R, 41G, 41B and the second coating liquid removal plate 42) are provided, but one first coating liquid removal plate corresponding to the color constituent colors having the same pattern shape may be provided. This will be described as a second embodiment.
In the pattern forming apparatus 1 according to the second examination technique , the configuration of the coating liquid removing unit 4 is different from that of the first examination technique described above. About the support part 5, it is the same as the 1st examination technique , The description is abbreviate | omitted.

(Coating solution removal unit)
In the coating solution removing unit 4 in the second examination technique , the first coating solution removing plate 41 and the second coating solution removing plate 42 are arranged on the circumferential surface of the body 40 so as to be aligned in the body rotation direction. Yes. The first coating liquid removal plate 41 is a plate provided with a convex portion a in a negative pattern of patterns Pr, Pg, and Pb having the same shape and constituting the combination portion P1. That is, since the negative patterns themselves of the patterns Pr, Pg, and Pb are the same, they are combined into one, and the first coating liquid removal plate 41 is used as one plate.
(Positioning, ink transfer removal-coating roller 2BM)
In the same manner as in the first embodiment described above, the application roller moving mechanism 2 in which ink is supplied from the application liquid supply unit 3 to the application rollers 2BM, 2R, 2G, and 2B starts moving toward the substrate support unit 5 side. Then, before the application roller 2BM is pressed against the second application liquid removal plate 42 of the application liquid removal unit 4, the portion where the application liquid of the application roller 2BM is transferred and removed, that is, the black ink formed on the application roller 2BM. The position adjusting means 8 aligns the second coating liquid removal plate 42 so that the convex portion a of the second coating liquid removal plate 42 corresponds to the negative pattern of the pattern P2.
When the positioning is completed before pressing by the application roller 2BM and the application roller 2BM comes into contact with the peripheral surface of the body 40 in this state, the movement of the application roller moving mechanism unit 2 is temporarily stopped, and the application roller Both the 2BM and the body 40 rotate in a synchronized state, the blanket 6BM of the coating roller 2BM presses the second coating liquid removal plate 42, and the convex portion a of the second coating liquid removal plate 42 causes the blanket 6BM. Then, the excess black ink is transferred and removed, whereby a pattern P2 made of black ink is formed on the coating roll 2BM.
When the transfer removal process for black ink, in which the pattern P2 is formed by the application roller 2BM by the alignment of the second coating liquid removal plate 42 and the transfer removal of the black ink, the application roller moving mechanism unit 2 moves again. The movement of the application roller moving mechanism unit 2 is continued until the application roller 2R and the first application liquid removal plate 41 correspond to each other in a non-contact state.

Subsequently, before the application roller 2R presses against the first application liquid removal plate 41 of the application liquid removal unit 4, the negative pattern of the pattern Pr made of red ink formed on the blanket 6R of the application roller 2R is changed to the first pattern. The body 40 is aligned by the position adjusting means 8 so that the convex portion a of the coating liquid removing plate 41 corresponds to the corresponding position. This positioning is completed before the application roller 2R is pressed, and when the application roller 2R comes into contact with the body 40 in this state, the movement of the application roller connecting / moving mechanism unit 2 is temporarily stopped. While the blanket 6R presses against the coating liquid removing plate 41, both of them rotate in a synchronized state, and the convex portion a transfers and removes the excess red ink from the blanket 6R of the coating roller 2R, thereby the blanket 6R. A pattern Pr made of red ink is formed.

The coating liquid at the position of the negative pattern is transferred and removed from the coating liquid, and a pattern Pg of green ink is formed by the coating roller 2G at a position corresponding to the position of the pattern Pg in the combination portion P1. The convex part a of the coating liquid removing plate 41 is made to correspond. That is, as in the case where the pattern Pr with the red ink is formed on the blanket 6R of the coating roller 2R, the portion of the coating liquid to be removed is located at the position of the negative pattern on the blanket 6G of the coating roller 2G. The position is adjusted so that the part a corresponds.
After the position adjustment, the blanket 6G of the coating roller 2G is pressed against the first coating liquid removing plate 41 (the state where the red ink is removed by the residual coating liquid removing device 7), and excess green ink is applied from the blanket 6G of the coating roller 2G. Is removed and a pattern Pg is formed on the blanket 6G.
(Residual coating solution removal)
When the transfer removal process at the application roller 2G is completed, the residual application liquid removing device 7 remains on the first application liquid removal plate 41 in the same manner as when the transfer removal process at the application roller 2R is completed. The green ink (green ink transferred and removed from the coating roller 2G) is removed, and the first coating liquid removal plate 41 is returned to a clean state.

(Positioning, ink transfer removal-coating roller 2B)
When the transfer and removal of the green ink on the coating roller 2G is completed, the coating liquid removing unit 4 is moved by the position adjusting means 8, and the coating liquid at the position of the negative pattern from the coating liquid on the blanket 6B on the next coating roller 2B. And the convex portion of the first coating liquid removing plate 41 so that the blue ink pattern Pb is formed by the blanket 6B of the coating roller 2B at a position corresponding to the position of the pattern Pb in the combination portion P1. Let a correspond. That is, at the position of the negative pattern on the blanket 6B of the coating roller 2B, the patterns Pr and Pg of the red ink and green ink are formed on the blankets 6R and 6B of the coating rollers 2R and 2G. The position is adjusted so that the convex portion a corresponds to the portion of the coating liquid to be transferred and removed.
After the position adjustment, the blanket 6B of the coating roller 2B is pressed against the first coating liquid removing plate 41 (the state where the green ink is removed by the residual coating liquid removing device 7), and excess green ink is applied from the blanket 6B of the coating roller 2B.

The pattern P2 is transferred to the surface of the substrate 50 from the blanket 6BM by rolling. When the pattern P2 is transferred, the coating roller 2R subsequently presses the surface of the substrate 50, and the pattern Pr formed on the blanket 6R is transferred to the surface of the substrate 50 while rolling (see FIG. 3). When the pattern Pr is transferred, the coating roller 2G subsequently presses the surface of the substrate 50, and the pattern Pg formed on the blanket 6G is transferred to the surface of the substrate 50 while rolling. Further, when the pattern Pg is transferred, the coating roller 2B subsequently presses the surface of the substrate 50, and the pattern Pb formed on the blanket 6B is transferred to the surface of the substrate 50 while rolling.

The pattern position is adjusted at the time of forming each pattern P2, Pr, Pg, Pb, and by the rotation of each coating roller 2BM, 2R, 2G, 2B in the transfer process. In addition, the blanket of the coating roller that comes later in the transfer order of the pattern to the substrate 50 comes into contact with the pattern previously transferred to the substrate 50, but the substrate 50 side is provided with a high strength to hold the coating liquid. Therefore, the application liquid does not re-transfer from the substrate 50 to the blanket (eg, made of silicone rubber) of the rear application roller. As one method for making the strength (adhesive strength) for holding the coating solution on the substrate 50 side larger than the peel strength between the blanket and the coating solution, a transparent adhesive on the surface of the substrate 50 is used.
