Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an electrode substrate for a multicolor electro-optic display device.

[Conventional technology]

Multicolor liquid crystal displays are used for TVs, various displays for combiator terminals, video camera monitors, car displays, etc.

An example of this multicolor liquid crystal display device is explained with reference to FIG. 2. A pair of transparent substrates (1) made of transparent glass or the like are arranged in parallel, and a plurality of striped transparent electrodes are arranged on both transparent substrates (1). (2) is on one transparent substrate (1) in the X-axis direction, and on the other transparent substrate (1) is in the Y-axis direction, so that the transparent electrodes (2) are orthogonal to each other. Like: bifurcated, and also small (transparent electrode (2) on one side)
A color filter (3) of three primary colors consisting of red (R), green (G), and blue (B) is provided above;
= A liquid crystal alignment layer (not shown) is provided according to the requirements, one liquid crystal (4) is filled between the two transparent substrates (1), and one liquid crystal (4) is filled between the two transparent substrates (1).
) is sealed with a sealing resin (not shown).

[Problem that the invention seeks to solve]

In the above-mentioned conventional multicolor liquid crystal display device, an image consisting of point-like pixels of three primary colors is displayed, and by additive color mixing by juxtaposed pixels of different colors (-), the eye (= multicolor image) is displayed. If it is possible to display the pixels of the mixed color, then the pixels of the mixed color are displayed, and the pixels of the mixed color are displayed. Although it is possible to display multicolor images close to natural colors, it is difficult to form such a display device.

Therefore, the problem that the present invention aims to solve is to significantly improve the mechanism of the current multicolor liquid crystal display device: multicolor electro-optics that enables display of multicolor images close to natural colors without changing the structure of the current multicolor liquid crystal display device. An object of the present invention is to provide an electrode substrate for an optical display device.

[Means for solving problems]

As a result of research to solve the above-mentioned problems, the present inventor discovered that by forming each colored pixel in the cross-sectional shape of a micro-convex lens, it is possible to display a multicolor image that is closer to natural colors. The present invention was completed based on these findings.

The electrode substrate for a multicolor electro-optic display device of the present invention is an electrode substrate in which a plurality of colored pixels of three primary colors are arranged on a glass substrate and a color filter is provided, and each colored pixel constituting the color filter is formed of a micro convex lens. It is formed in a cross-sectional shape.

FIG. 1 shows a multicolor liquid crystal display f2k formed using the dragon electrode substrate for a multicolor electro-optic display device of the present invention.

As shown in the first diagram, one transparent substrate made of glass or the like (
1) Each colored pixel of a color filter (6) is formed in the cross-sectional shape of a micro convex lens on a transparent electrode (2) of a predetermined shape.

Microphone: As a colored pixel with a cross-sectional shape of a convex lens, the support is composed of a screen made of stainless steel fiber or polymer fiber, and the two-hole part is a screen plate for stencil printing made of stainless steel made of resin or thin metal plate, or a thin metal plate). A screen plate for stencil printing with openings formed therein is used, and a screen plate formed by the stencil printing method is applied. Water-based ink and oil-based ink can be used as the material for forming the colored pixels.

For example, in the case of water-based dye ink, a mixture of dye, pvA, ethylene glycol, etc. is used, and in the case of water-based pigment ink, a mixture of pigment, PVA, ethylene glycol, etc. is used.

Further, as the oil-based ink, oxidative polymerization type ink and UV ink can be used.

[Effect]

The colored pixels in the shape of micro convex lenses have the effect of imparting a dichroic shape (displayed image) under the state in which an electric field is applied between the electrodes and refracting the original color to mix the colors of the colored pixels arranged in parallel. It is something to do. The mixed color light passes through the oriented liquid crystal layer and then through the double-stranded light layer to the viewer's eyes, where a multicolor image is viewed.

〔Example〕

/, /mrnt glass substrates were film-formed with a film of 1 oooh of ITO and patterned into a predetermined shape to produce transparent electrodes.

Next, red ink was prepared using Papam Red HF-JB, Seiryoku Fast Yellow M, PVA, and ethylene glycol (;), and the stencil part was prepared using electroforming on a stainless steel screen with 200 mesh and 0 bias. Using a screen plate for stencil printing, in which a nickel stencil with a thickness of μmt is bonded with plating, the red ink is accurately aligned at a predetermined position on the transparent electrode substrate, and the cross-sectional shape of the micro convex lens of the first color is colored. formed a pixel.

Next (a green ink consisting of Nirio Fur Grishiko YS, Seiry Fast Ero-M, PVA, and ethylene glycol was prepared, and the green ink was precisely aligned using the same screen plate for stencil printing as described above. second than two

A colored pixel with a cross-sectional shape of a micro convex lens of the eye was created, and a color filter consisting of colored pixels of three primary colors was created.The orientation treatment was performed to align the opposing electrodes. After sealing, liquid crystal was injected to produce a multicolor liquid crystal display of the present invention.

The multicolor liquid crystal display device of the present invention had excellent characteristics in terms of overall color tone and two.

〔Effect of the invention〕

As detailed above, the electrode substrate of the present invention forms a multicolor electro-optical display device that can display multicolor images closer to natural colors than before without significantly changing the display mechanism. can do.
