て画素を形成する方法も試みられている。Conventional technology Conventional color filters are made by imparting photosensitivity to denatured proteins such as gelatin, casein, or synthetic dyeing resins on transparent glass to create pixel patterns, and then dyeing them. There is a method of attaching a pigment to the transparent electrode of the transparent glass by configuring a transparent electrode on top of the transparent glass, applying a voltage to the transparent electrode, and submerging the transparent glass in a liquid in which the pigment is dispersed. A method of forming pixels by printing has also been attempted.

It is composed of transparent glass 6 with PT, and has a spacer of 10 to 50 μm as a spacer to maintain the thickness of the liquid crystal layer at a predetermined value (about 5 μm) over the entire surface of the liquid crystal display.
It is common to disperse in the liquid crystal layer a large number of glass fibers cut into lengths whose outer diameters match the thickness of the liquid crystal layer.

定の液晶層厚が得られるような値にする。EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings. FIG. 1 shows a color filter for a liquid crystal display according to an embodiment of the present invention. In the color filter of the present invention, pixels 2 of each of the three colors red (R), green (G), and blue CB) are formed on a transparent glass plate 1 by a dyeing method, an electrodeposition method, a printing method, etc., and then The black light-shielding film 3 is provided by a printing method. Hereinafter, a method of exploding a color filter for a liquid crystal display will be explained in the order of steps with reference to FIG. As shown in FIG. 2a, pixels 2 of three colors R, G, and B are alternately formed in a mosaic on a transparent glass plate 1. Next, as shown in b, a black light-shielding film 3 is formed in the gap between each pixel 2 by a printing method. Printing is performed by intaglio printing in which the printing thickness of the ink, which is the material of the black light-shielding film, can be changed, and the protrusions 4 of the black light-shielding film and the other parts 3 are printed at the same time. Since it is generally impossible to change the thickness of the ink using other methods such as screen printing and planographic printing, it is possible to use two plates for the protrusions and other areas, and overprint only the protrusions. Let's do it. The height of the protrusion 4 is set to such a value that a predetermined liquid crystal layer thickness can be obtained when another transparent glass plate 6 on which TPT is formed is stacked.
又、突起４？′ｉ黒色遮光膜３の全域ではなく、その一

全域に分散しているが、透明ガラス板１上に、黒色遮光

形成後、第２図Ｃのように保護膜、透明電極、配向膜等
順次積層した多層膜６を形成する。Also, protrusion 4? 'i It is formed not over the entire area of the black light-shielding film 3, but only in a part thereof. In FIG. 1, the protrusions 4 are dispersed over the entire area of the black light-shielding film, but they may be formed on the transparent glass plate 1 at the four corners of the area occupied by the black light-shielding film 3. After forming the black light-shielding film, a multilayer film 6 is formed by sequentially laminating a protective film, a transparent electrode, an alignment film, etc. as shown in FIG. 2C.
あるいは黒色遮光膜を平坦に形成した後、保護膜、透明
電極、配向膜等を積層し、その上に再び黒色遮光膜に相
当する部分の上に突起を印刷により形成してもよい。Alternatively, after the black light-shielding film is formed flat, a protective film, a transparent electrode, an alignment film, etc. may be laminated, and then projections may be formed again by printing on the portions corresponding to the black light-shielding film.

現できる。If the color filter described above is overlapped with a separately manufactured transparent glass plate mounted on a TFT tower, the distance between the two glass plates is regulated by the height of the protrusion of the black light-shielding film of the color filter, and the entire surface of the glass plate is covered. Uniform spacing can be configured. By sealing the periphery of the two glass plates with an adhesive or the like and then injecting liquid crystal, a liquid crystal display with a uniform thickness of the liquid crystal layer over the entire glass surface and excellent display performance can be realized.
