を用いていた。2. Description of the Related Art Conventionally, a printing method has been adopted as a method for manufacturing a color filter of this type because of its low cost and mass productivity. As for the printing method, as shown in FIG. 1 (a), a patterned intaglio 1 is installed, and while the excess color filter ink is scraped off by the blade 3 onto the image area of this intaglio 1, the color filter ink 2 Attached, Fig. 1 (b)
As shown in FIG. 1, the elastic rubber roller 4 mounted on the plate cylinder 5 is pressed against the intaglio 1 to transfer the color filter ink 2 onto the surface of the rubber roller 4, and
As shown in (c), the rubber roller 4 is pressed against the transparent glass substrate 6 which is the substrate to be printed, which is adsorbed and fixed on the substrate to be printed (not shown). The offset printing method in which the ink 2 for color filter was transferred was used.

び緑の各色要素層のパターン精度が悪くなっていた。By the above printing method, the color element layers are printed so as to have a predetermined pattern, then dried / cured, and this is repeated, and the red, green, and blue color element layers are mosaic-shaped or stripe-shaped at predetermined intervals. Etc. to produce a color filter. In such a manufacturing method, the color element layer on the intaglio 1 is once transferred to the rubber roller 4 which is an elastic body, and then transferred again to the transparent glass substrate 6, so that the color filter ink 2 is rotated twice. I have to move. Therefore, even if the pattern accuracy of the intaglio plate 1 is increased, ink bleeding due to printing pressure at each transfer, deformation of the rubber roller, ink agglomeration, and the like cause the red, blue, and green color element layers to be separated. The pattern accuracy was poor.

る方法をとっていた。For the above reasons, a direct printing method in which a color roller ink is applied to a patterned rubber roller and then the plate cylinder is directly pressed against the substrate to transfer the color filter ink to the substrate. Was also used (see Figure 2). First, a color filter ink is formed on a thin film on another substrate, and the rubber roller 4 is placed on the substrate.
Then, as shown in FIG. 2, the recess 7 is filled with the color filter ink 2. Next, the rubber roller 4 having the concave portion 7 filled with the color filter ink 2 is placed on the glass substrate 6 which is the color filter forming portion, and rolled to roll the color filter ink 2 filled in the concave portion 7 to the glass substrate 6. No. 6, and heat treatment was performed to form a color filter.

ルタができない。この線幅のムラがでるため、細いフイ
ルタを構成することが難しいという問題があった。However, when printing on a glass substrate using this printing method, the plate cylinder had to have elasticity in order to prevent damage to the substrate. Therefore, the elastic layer is deformed by the printing pressure during printing, and the pattern accuracy of the color element layer printed on the substrate to be printed is poor. In particular, when printing is performed on a substrate to be printed having a front color element layer, the elastic layer rises up, the elastic layer is largely deformed and the color element layer does not sufficiently contact the substrate to be printed, The deformation of was also great. Further, due to the variation of the pressure applied to the rubber roller 4, the line width of the formed striped filter becomes uneven, and a uniform filter cannot be obtained. Since the line width is uneven, it is difficult to form a thin filter.

った。Even when the printing pressure during printing is increased, the deformation of the elastic layer corresponding to the thickness of the color element layer adjacent to the color element layer remains,
The deformation of the color element layer was large. When the printing pressure is weakened to eliminate the deformation of the color element layer, a new problem of defective ink adhesion occurs, and therefore the deformation cannot be eliminated by this method. The waterless planographic printing plate in which a rubber layer having a thickness of about 0.25 mm was provided below the ink repellent layer in order to impart elasticity to the plate had a large surface roughness of the rubber layer, so that the plate making precision itself was poor.

FIG. 4B is a diagram showing a cross section of FIG. First, red stripe pixels are printed by the process shown in FIGS. 2 and 3. In FIG. 2, the rubber roller 4 is provided with a recess 7. The width is 70 μm to 95 μm and the period is about 300 μm. Ink for color filter 2
Is supplied to the concave portion 7 at a position deep in the paper surface of FIG. 2 (the supply mechanism is not shown) and comes out to a position in front of the paper surface. Then, the color filter ink 2 is transferred to the glass substrate 6.

The second color, green, is printed on the glass substrate 6 on which red pixels (referred to as front pixels 9) are printed, but the pressure is applied to the rubber roller 4 as in the conventional method, and the color filter ink 2 is used. When the glass substrate 6 is brought into contact with the glass substrate 6, the pressure on the contact surface becomes non-uniform, the pixels of the green stripe become non-uniform, and defects such as flaws, pinholes, white spots, and steps are generated.

線を設けておくことが好ましい。FIG. 5 shows the method of the present invention. FIG. 5 (a)
When the color roller ink 4 is brought into contact with the glass substrate 6 through the space 8 corresponding to the thickness of the front pixel 9 by weakening the pressure of the rubber roller 4 as shown in FIG.
Due to the stress caused by the difference in contact angle between the color filter ink 2 and the rubber roller 4 and the contact angle between the glass substrate 6 and the color filter ink 2 (hysteresis of the contact angle), the color filter ink 2 becomes rubber. The surface of the roller 4 is transferred to the surface of the glass substrate 6. That is, as can be seen from the side view shown in FIG.
Exists between the front pixels 9, and the surface of the rubber roller 4 other than the concave portion 7 is in contact with the surface of the front pixel 9. At this time, no strong pressure is applied to the rubber roller 4, so that even if the color filter ink 2 is brought into contact with the glass substrate 6 by the difference in surface tension, the pressure on the contact surface is small and the rubber roller 4 is distorted. Since the color filter ink 2 is uniform without being formed, the inconvenience of causing flaws, pinholes, white spots, steps and the like in the stripe-shaped pixels of the color filter ink 2 is eliminated. If there is a very small portion that the color filter ink 2 is in direct contact with without interposing a space, the transfer of the color filter ink 2 thereafter will not be cut off and will continue easily, so that the edge is orthogonal to the stripe. It is preferable to provide a line having a width of about 50 μm and the same thickness as the pixel.

のパターンがそのまま被印刷基材上に転写される。The hysteresis of the contact angle is preferably 10 ° or less, and if it exceeds 10 °, the color filter ink 2 remains on the rubber roller 4, so that it becomes difficult to maintain the flatness of the surface of the pixel and the desired film is formed. It tends to be difficult to obtain thick pixels. As a result, the contrast of the liquid crystal panel is reduced. By heating each color element layer formed at a predetermined interval on the plate by the ink inking process, the stress caused by the hysteresis of the contact angle is applied to transfer the ink of each color element layer on the plate, and the predetermined color is formed on the plate. The pattern of each color element layer formed at intervals is directly transferred onto the substrate to be printed.

ことになる。Therefore, without strongly applying the printing pressure,
Since each color element layer is formed at a predetermined interval from the plate on the substrate to be printed by non-contact and single ink transfer, the pattern accuracy of each color element layer can be made as high as the pattern accuracy of the plate. In addition, the pattern of the color element layer has no defects, and a liquid crystal display panel with high contrast can be realized.

FIG. 3 is a process diagram of a method for manufacturing a color filter according to the present invention. 5A is a front view and FIG. 5B is a side view. As shown in FIG. 2, the inking of the ink is performed by the rubber roller 4
Recesses 7 are formed at predetermined intervals, and the recesses 7 are filled with the color filter ink 2. Ink on other plates is scraped off. First, the recess 7 is filled with the color filter ink 2 in the shape of the red stripe shown in FIG.
On the surface of the glass substrate 6, the color filter ink 2 in the shape of a red stripe could be printed orderly. First color (red)
Since there is no front pixel, the glass substrate and the rubber surface contact and the red color filter ink 2 contacts the rubber surface,
Red stripe pixels can be formed. At this time, since the printing pressure is applied uniformly, the red stripe-shaped pixels are free from scratch deformation defects. Since the front pixel 9 in FIG. 5A does not exist, a flat and uniform red stripe could be formed. Next, the green color filter ink 2 is filled in the recesses 7 for printing. At this time, since the red front pixel 9 exists, the rubber roller 4 stops on the surface of the red front pixel 9 and does not contact the surface of the glass substrate 6. The green color filter ink 2 faces the surface of the glass substrate 6 through the space 8. In this state, the green color filter ink 2 separates from the rubber roller 4 and contacts the surface of the glass substrate 6.
Blue went the same way. FIG. 5B is a side view at this time, in which red and green (9 in all) of the front pixels are arranged on the surface of the glass substrate 6 and spaces 8 are present at equal intervals. The color filter obtained by heating and ultraviolet curing has the form shown in FIG. The rubber roll 4 is kept at 80 ° C. for both red, green and blue, and the surface of the glass substrate 6 is also kept at 80 ° C.
