Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a color filter used in a color liquid crystal display panel or the like, and more particularly to a method of manufacturing a colored pixel using a printing technique.

Liquid crystal display panels having characteristics such as thinness, light weight, and low power consumption have been rapidly popularized in recent years and used in various fields. Especially, the market trend is large screen,
As the demand for high-definition and color is increasing, and in the future as demand continues to expand, it is necessary to supply high-performance color liquid crystal display panels at low prices.

[0003]

2. Description of the Related Art A color filter used for a color liquid crystal display panel or the like generally has three color red (R), green (G) and blue (B) pixels formed on a glass substrate, and steps and gaps between the pixels are formed. A flattening layer for filling is formed.

Color pixels are manufactured by a pigment dispersion method using a resin in which a pigment is dispersed, a dyeing method in which gelatin or the like is dyed with a dye, and an electrodeposition method in which a transparent electrode is formed and the surface is colored by an electrophoretic method. Is generally known.

The pigment dispersion method includes a method utilizing a photolithography technique and a method utilizing a printing technique. In any case, it is necessary to repeat the same process three times for each color of red, green and blue.

[0006] A conventional color filter uses a photo-ultraviolet (UV) curable coloring resin in which a pigment is dispersed, and uses a photolithography technique which is excellent in terms of pixel pattern accuracy and uniform pixel thickness. Is widely adopted,
Since the application of the resin solution and its pre-baking, the application of the oxygen barrier film and its baking, exposure, development, and the post-baking of the resin solution are performed for each color of the pixel, the manufacturing process is complicated and the cost is high. is there.

On the other hand, the method of using a printing technique using a colored resin (ink) in which a pigment is dispersed can be manufactured at low cost, but technically in terms of pixel pattern accuracy and uniform pixel thickness. There is a problem to be solved, and it has not yet reached the stage of practical use.

FIG. 9 is a sectional view of a color filter, and FIG. 10 is an explanatory view of a conventional pixel manufacturing method by a printing method. Figure 9
Color filter 1 used in liquid crystal display panel
After forming the black mask 3 on the surface of the transparent substrate (glass substrate) 2 and forming the colored pixels R, G and B so as to fill the through holes of the mask 3, the gap between the pixels R, G and B is formed. And a flattening layer 4 is formed to eliminate the step between the pixels R, G and B.

FIG. 10 (a) is an explanatory view of a pixel printing method using an intaglio cylinder. The colored transparent resin ink 7 filled in the recess 6 of the rotating intaglio cylinder 5 is synchronized with the rotation of the plate cylinder 5. Print on the moving substrate 2.

In the printing method, the recess 6 is formed on the plate cylinder 5.
The ink 7 is provided on the releasable layer so that the ink 7 easily peels off. However, when the viscous paste-like ink 7 is printed on the substrate 2, the ink 7 may have thread-like whiskers 7'as shown in the drawing. , A part 7 ″ of the ink 7 remains in the recess 6.

Therefore, in the pixels R, G, and B on which the ink 7 is printed on the substrate 2 and hardened, the ink amount is partially insufficient, or the tip of the whiskers 7'protrudes out of the pixel area. In addition, since the fluidization occurs before the curing process, the pattern shape may be broken or the thickness may be uneven.

FIG. 10B is an explanatory view of a pixel printing method using a blanket, in which the ink 7 of the flat intaglio 9 is transferred to the blanket 8 and the ink 7 of the rotating blanket 8 is transferred.
Is pressed against the substrate (2) that moves in synchronization with the blanket 8 for printing.

In the printing method, the recess 6 of the intaglio 9 is formed.
Is provided on the release layer of the intaglio plate 9 so that the ink 7 can be easily peeled off. When the ink 7 is transferred to the blanket 8 and when the ink 7 of the blanket 8 is printed on the filter substrate, the ink 7 forms a thread. The ink 7 transferred to the blanket 8 may be pulled or partially left in the recess 6.
However, as shown in the drawing, the liquid flows so as to spread, so that the pixel R, G, and B can have a distorted pattern shape or uneven thickness, as in the printing method using the intaglio cylinder 5.

[0014]

As described above,
The method of forming pixels by the printing method is simpler in manufacturing process and superior in mass productivity than the method using the photolithography technique, but on the other hand, the thread-shaped whiskers 7 ′ as shown in FIG.
There is a problem in that it is difficult to form an accurate pattern because the printed pattern and the blanket undergo a flow deformation as shown in FIG. It was

[0015]

FIG. 1 is an explanatory view of the basic constitution of the method of the present invention using a plate cylinder. In Figure 1 (a),
The rotating plate cylinder 5 has a large number of recesses 6 formed in the releasable layer on the surface thereof, and the recesses 6 are filled with a transparent colored resin ink 7.
The color filter forming temporary substrate (glass substrate) 2 that presses is moved in the left-right direction.

Then, the ink 7 at the contact portion between the substrate 2 and the plate cylinder 5 is printed on the substrate 2 and at the same time, a curing process is performed. For example, when the ink 7 is photocurable, light 11 necessary for curing is passed through the substrate 2. Irradiate.

Therefore, the hardened ink (pixel) 71 which is hardened at the same time as printing on the substrate 2 has substantially the same shape as the recess 6, and is hardened while maintaining this shape. Figure 1
In (b), after the ink 7 is filled in the recess 6 of the rotating plate cylinder 5, a suitable semi-curing treatment is applied to the ink 7, for example, a certain thermosetting ink 7 is heated at 100 ° C. for about 5 minutes. The ink 72 is heated to be dried, and the ink 72 is printed on the substrate 2 by utilizing the adhesive force of the dried ink 72.

Therefore, the raw dry ink 72 printed on the substrate 2
Has substantially the same shape as the recess 6, and by completely curing it, a cured ink (pixel) having the substantially same shape as the recess 6 is formed on the substrate 2.

As shown on the left side of FIG. 1C, after the ink 7 is filled in the recess of the plate cylinder 5, a curing process of the ink 7, for example, a light 11 required for complete curing when the ink is photocurable.
To complete cure ink 71.

Therefore, an adhesive is applied to the ink 71 or an adhesive is applied to the surface of the substrate 2, and the adhesive 14 is used to cure the cured ink (as shown on the right side of FIG. 1C). Pixel) 71 is adhered to the substrate 2.

Although FIG. 1 describes the method of printing one type of ink 7, a color filter is completed by sequentially printing multicolor inks such as transparent red resin ink, transparent green resin ink, and transparent blue resin ink. To do.

[0022]

According to the above means, since the ink is cured or dried in the plate recess, ink whiskers and residue in the recess in the conventional method can be eliminated, and the flow after printing can be eliminated. An accurate pixel based on the location can be formed.

The size of the pixel (plate recess) in the color filter is about 50 μm to 1000 μm in both width and length. Therefore, when the plate cylinder is used, the surface of the ink that has been cured in the recess will bend with the curvature of the plate cylinder, but by slightly increasing the radius of curvature of the plate cylinder,
Bending due to the curvature can be ignored.
