Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing plate for manufacturing a black matrix and color pixels of a liquid crystal color filter with high accuracy by reducing the line width disturbance by a printing method, a plate making method thereof, and a color filter. Related to a manufacturing apparatus.

[0002]

2. Description of the Related Art In general, in a liquid crystal color filter, in order to increase the contrast of a screen and make it easier to see visually,
A black matrix (light-shielding portion) is provided between the color pixels. As a material of the black matrix, a metal having a low reflectance such as chromium, nichrome, tantalum or the like is mainly used. FIG. 7 shows a general production example of a conventional black matrix using metallic chromium. In this method, a chromium vapor-deposited film (thickness: about 0.1 μm) is formed on the entire surface of the glass substrate 7-1 by vapor deposition or sputtering.
After forming 7-2, a photoresist film 7-3 is formed by a spin coater (not shown). Next, the light-shielding mask 7-4 is brought into close contact with the photoresist film 7-3, and in this state, the irradiated portion is light-cured by irradiating the ultraviolet light 7-5. Thereafter, the unexposed portion of the photoresist film 7-3 is removed with a solvent, and the chromium deposition film 7-2 of the unexposed portion is removed by dipping in an etching solution. The black matrix is manufactured by removing the.

However, in this method, after forming a metal thin film in vacuum, a pattern is formed by photolithography and etching, so that the number of steps is increased and productivity is poor. Further, there is a disadvantage that equipment costs such as sputtering, vapor deposition and etching equipment are expensive. For this reason, the manufacturing cost of the color filter is about 6,000 yen (14 inches, TFT
), The cost of chromium deposition is about 130
It occupies 0 yen, and there is a demand for the production of a low-cost black matrix. On the other hand, there has been proposed a method of providing a black matrix at low cost by a printing method. This involves printing a pattern of organometallic resinate (organic metal in which metal is bonded to an organic chain such as copper mercaptide) on a glass substrate by lithographic printing or intaglio printing, and firing it to produce a mixture of metal / nonmetal oxide. (For example, Japanese Patent Application No. Hei.
No. 66272). However, in this case, since it is a metal-based paste, a high-temperature sintering furnace is required because the sintering conditions are 530 ° C. × 30 minutes. And productivity has not always been improved.

Next, color pixels are formed between black matrices. If the color pixels are formed by a pigment dispersion method, an electrodeposition method, or the like, the accuracy is high, but the productivity is low. Therefore, recently, color pixel film formation is performed by a printing method (for example, Japanese Patent Application No. 1-117525).
issue). FIG. 8 is a front view of a conventional color pixel film forming printing press. In the above printing machine, a glass substrate 8-1 on which a black matrix has been applied in advance is placed on the left end of the gantry 8-2, and the printing plate 8 for color pixels is
-7 is for red 8-7- and green 8-7- in order
And a movable frame 8 containing a press cylinder 8-5, a blanket cylinder 8-4, and an inking roller 8-6- for the three colors on the right side. -3 are respectively installed.

[0005] As a printing procedure of the color filter, first, the movable base 8-3 moves to move the ink forming roller 8-6.
To transfer the ink to the printing plate 8-7-. afterwards,
The ink is transferred from the printing plate to the blanket cylinder 8-4. Such an operation is repeated for the remaining two colors. After the three color pixels are transferred onto the blanket cylinder 8-4, finally, the three color pixels are simultaneously printed on the glass substrate 8-1. Thereafter, in order to smooth the ink film of the color pixels, pressing is performed by the press cylinder 8-5, and printing is completed. The position of the fine line to be printed on the glass substrate 8-1 is determined by the position of the glass positioning actuator 8-
8 and the plate positioning actuators 8-9--8. Here, in the conventional printing method, the ink on the printing plate 8-7 is
-4 and then printing on the glass substrate 8-1 is the mainstream lithographic offset printing method.

As described above, since the black matrix and the color pixels are applied by a printing method as a method of manufacturing a color filter, productivity is improved as compared with the conventional pigment dispersion method and electrodeposition method, and The cost of the liquid crystal color filter of the related art can be reduced to about half by printing color pixels for about 6,000 yen by the conventional method. As described above, the conventional printing method of the black matrix and the color pixels has a cost advantage, but has a problem that the accuracy of the stripes of the black matrix and the color pixels is lower than the pigment dispersion method.

[0007]

The problems of the conventional color filter printing method will be described below. That is,
A conventional plate used for lithographic printing of a black matrix and color pixels is generally a waterless plate, which is a method of forming an image portion to which ink adheres by a brush developing method. FIG. 9 shows a conventional plate making method for a waterless plate. The structure of the waterless plate is an aluminum substrate (240 μm ^t ) 9
-4, a photosensitive layer (1 μm ^t ) 9-3, a silicone resin (1 μm ^t ) 9-2 having ink repellency,
It is composed of a cover film (100 μm ^t ) 9-1. A positive film 9-5 is superimposed on this and irradiated with ultraviolet light 9-6, whereby optical bonding is performed between the silicone resin 9-2 and the aluminum substrate 9-4 in the light passing portion. Then, a light bonding portion 9-7 is formed. next,
The uncured silicone portion 9-9 is mechanically peeled off by the developing brush 9-8 and removed. Here, the developing brush 9-
As the material 8, a resin material such as nylon is used. As a result, the silicone portion (non-image portion) to which the ink does not adhere 9
-10 and a photosensitive layer (image area) 9-11 to which ink adheres
Is formed to form a printing plate. Here, the non-image area 9-10
Looking at the shape, the silicone on the photosensitive layer 9-11 is basically formed as a single rubber sheet, and the portion which is not bonded to the aluminum substrate 9-4 is replaced with the developing brush 9-8. Non-image area 9-
The edge sharpness 9-12 of No. 10 is uneven and bad, and the width of the non-image portion 9-10 partially changes. When this plate is printed, the unevenness of the non-image areas 9-10 is transferred to the glass substrate as it is, so that there has been a problem that the precision of the line width of the printed fine line deteriorates.

FIG. 10 shows this state in the case of a black matrix. This black matrix printing plate has a structure in which a photosensitive layer 10-2 is provided on an aluminum substrate 10-1, and a silicone resin 10-3 is provided thereon.
Are formed. Here, in order to print the required ink film thickness, the recess depth 10-4 for the black matrix is set to a predetermined depth (about 2 μm), and the recess line width 10-4 is set.
-5 is also formed with a predetermined width (15 to 25 μm).
However, as described above, since the edge sharpness is poor,
The line width of the printed black matrix varies, and a portion having a large line width (maximum line width) 10-6 and a portion having a small line width (minimum line width) 10-7 are generated. Therefore, since the line width of the black matrix is not constant, the aperture area ratio (the area other than the black matrix) is different at each location, and there is a problem in that unevenness in the amount of light occurs when incorporated into a liquid crystal panel.

The construction of the printing plate for color pixels shown in FIG. 11 is basically the same as that of the black matrix described above. A photosensitive layer 11-2 is provided on an aluminum substrate 11-1 and a silicone resin 11-3 is provided thereon. Are formed. Here, in order to print the required ink film thickness, the color pixel recess depth 11-4 is set to a predetermined depth, and the recess line width 10-5 is also formed to a predetermined width. However, as described above, since the edge sharpness is poor, even in the case of a color pixel, as in the case of the black matrix, the line width of the color pixel is 11-6 (the maximum line width) and 6-12 (the minimum line width). 7 results. If the line widths of the color pixels are not constant, when printing each of the three colors of red, green, and blue, a certain pixel protrudes into an adjacent pixel, causing a problem that color unevenness of the color filter occurs as a whole.

[0010] The present invention has been made in view of such circumstances, and an object thereof is to solve the above problems.
Instead of the brush development method, which is a conventional printing plate making method, a thin plate-shaped disk-shaped cutter is used to finely engrave the intaglio portion to make a printing plate of black matrix and color pixels with high precision. Another object of the present invention is to provide a color filter printing plate for producing an inexpensive liquid crystal color filter of excellent quality, a plate making method thereof, and a color filter manufacturing apparatus.

By removing the line layer by cutting, a striped or lattice image portion is formed. In the present invention of claim 2, the image layer is formed on the substrate, a non-image layer is formed on the image layer, and the non-image layer is partially cut to form the image layer.

Here, FIG. 1 is an explanatory diagram of a plate making method (hereinafter, referred to as a micro-cutting method) using a thin blade cutter for making a plate for printing a black matrix and color pixels with high precision according to an embodiment of the present invention. 2 and 3 are plate making situation diagrams according to the embodiment of the present invention, FIG. 4 is a configuration diagram of a micro-cutting plate making apparatus used in the embodiment of the present invention, and FIG. 5 is a diagram showing a printing plate made in the embodiment of the present invention.

FIG. 1 is a basic conceptual diagram of a micro-cutting system according to an embodiment of the present invention, which can make a printing plate of a black matrix and color pixels with high precision. The plate making method according to the embodiment of the present invention is greatly different from the conventional plate making method in that the wheel type cutter 1-1 is rotated at a high speed in place of the conventional brush development so that the silicone resin 1-6 to be removed is formed in a groove shape. To form a grid pattern of a black matrix or a stripe pattern of color pixels with high precision. As the printing plate, a waterless plate is used as in the prior art. More specifically, the wheel-type cutter 1-1 is composed of a hard abrasive grain 1-2 such as diamond and a resin or metal binder 1-3 holding the hard abrasive grain 1-2 in order to accurately cut silicone. I have.

The wheel type cutter 1-1 is mounted on a rotating shaft 1-4 installed above a printing plate 1-5, and is rotated at a high speed via the rotating shaft 1-4 to make the same printing plate 1-1.

The lower limit of -8 does not need to be limited to this value, and may be smaller. The cutting pattern is obtained by cutting grooves in one direction, rotating the printing plate by 90 degrees, and cutting at a predetermined pitch in the direction orthogonal to the grooves in order to engrave in a grid pattern for a black matrix.

In the method of making a printing plate for color pixels, FIG.
As shown in the above, cutting is performed by a wheel-type cutter 3-9 as in the case of the black matrix printing plate. At this time, the difference from the black matrix printing plate is that the required thickness of the color pixels is about 4 μm, which is thicker than the black matrix of 1 μm, so that the silicone layer 3-10 in the concave portion is as thick as 12 μm. . The non-image area width pitch 3-11 is about 300 μm, and the image width 3-12 of the color pixels is 100 μm.

Further, with the cutting, there is a possibility that chips generated by cutting may adhere to the upper portion of the printing plate 4-3, so that pure water is sprayed from the cutting powder removing water supply hose 4-7 to print the printing plate. The surface of 4-3 is cleaned. For this reason, the base end of the supply hose 4-7 is connected to a water supply source (not shown), and the front end is provided to be located above the printing plate 4-3.

According to the micro-cutting type plate making method of the black matrix and color pixel printing plate of the present embodiment having the above-described configuration, the edge sharpness of the line width is greatly improved as follows. First, the line width accuracy of the black matrix has been improved. That is, a thin disk-shaped cutter with a cutter thickness of 15 μm can be rotated at high speed, and the silicone resin of the printing plate can be cut with high precision using fine diamond of hard abrasive grains of the cutter. Because the brushes did not remove the silicone that had not adhered and the silicone, the accuracy of the edge sharpness of the line width on the plate was greatly improved. Printing on a glass substrate using this printing plate resulted in the following. Conventional brush developing method Average line width: 15 μm Line width variation: ± 1.5 μm Micro-cutting method according to the embodiment of the present invention Average line width: 15 μm Line width variation: ± 0.7 μm This is represented by (line width variation) / If the edge sharpness ratio is defined as (average line width), as shown in FIG. 6, the edge sharpness of the conventional brush developing method is 0.2, whereas the embodiment of the present invention is about 0.02, which is about twice as large as 0.2. It can be seen that the edge sharpness has been improved. Second, the line width accuracy of the color pixels has been improved. That is, the printing state of the color pixels was improved in the accuracy of the printing line width similarly to the black matrix as follows. Conventional brush developing method Average line width: 100 μm Line width variation: ± 15 μm Micro-cutting method of the embodiment of the present invention Average line width: 100 μm Line width variation: ± 5.5 μm In contrast to 0.3, in the embodiment of the present invention, 0.11 and about 3
It can be seen that the edge sharpness was improved by a factor of two. In addition, in the conventional developing method, the line width variation of the color pixels is larger than that of the black matrix, and the accuracy is poor.
The thickness of the non-image area silicone is 2 μm for the black matrix plate, but 12 μm for the color pixel plate to transfer the thick film ink. This is because silicone is more likely to peel and the edge sharpness is degraded.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and changes may be made without departing from the scope of the present invention. What you get.

[0025]

As described above, the color filter printing plate according to the present invention is a plate having an image layer and a non-image layer on a substrate, and the non-image layer is removed by cutting. Thus, a striped or lattice image portion is formed. Further, the plate making method of a color filter printing plate according to the present invention includes forming an image layer on a substrate, forming a non-image layer on the image layer, and partially cutting the non-image layer. By doing so, the image layer is exposed to form a stripe or lattice image portion. Furthermore, the apparatus for manufacturing a color filter according to the present invention is a plate having an image layer and a non-image layer on a substrate, and by removing the non-image layer by cutting, a stripe-shaped or lattice-shaped A printing plate having an image portion formed thereon, and a light-shielding portion printing unit for forming a light-shielding portion pattern on the substrate, and a substrate having the printing plate and having the light-shielding portion pattern formed on the substrate A pixel printing unit for continuously printing a color pixel pattern. Therefore, according to the micro-cutting plate making method of the present invention, the precision of the printed fine line is improved as compared with the conventional brush developing method. As a result, the following advantages have been brought about in terms of color filter production. In the conventional black matrix film formation by brush development, the line width was large and the line width was large, so that the line width was large and the line width was small. The area ratio changed little at each location, the problem of uneven light quantity was reduced, and the manufacturing yield was improved. In addition, since line width variation is large in conventional color pixel film formation by brush development, when three colors of red, green, and blue are printed, a certain pixel protrudes into an adjacent pixel, so that color unevenness of the color filter as a whole is caused. However, the production yield of the color film was improved because the line width was made constant by the present invention.
As a result, the production cost of the color filter 10 finally becomes about 2,000 yen in the present invention, and the cost can be reduced to one half of the conventional printing method using brush development. An inexpensive liquid crystal color filter with excellent quality was manufactured.
