Abstract

A color filter substrate for a liquid crystal display device, includes a transparent substrate, a black matrix formed on the transparent substrate and having an opening for division into a plurality of pixels, a transparent conducting film, and a color layer formed on the pixel, wherein a linear projection is formed in a center of the pixel and a recess is formed above the black matrix.

Claims (15)

1. A color filter substrate for a liquid crystal display device, comprising:

a transparent substrate;

a black matrix formed on the transparent substrate and having an opening for division into a plurality of pixels;

a transparent conducting film coated over the black matrix and coated over the transparent substrate; and

a color layer formed on a pixel of the plurality of pixels, wherein

a linear projection is formed in a center of the pixel, the linear projection being a laminated constitution of

a linear resin layer formed in the center of the pixel, and

the color layer,

the laminated constitution of the linear resin layer and the color layer is laminated in an order of the linear resin layer and the color layer, and

a recess is formed above the black matrix and is formed by a step between the adjacent color layers.

2. The color filter substrate for a liquid crystal display device according to claim 1 , wherein the color layer includes three color layers formed of a red pixel, a green pixel, and a blue pixel formed on the respective pixels.

3. A liquid crystal display device, comprising: the color filter substrate for a liquid crystal display device according to claim 1 .

4. The liquid crystal display device according to claim 3 , wherein the liquid crystal display device comprises the color filter substrate for the liquid crystal display device, an array substrate on which drive elements for liquid crystals are disposed in a matrix arrangement, and a liquid crystal layer interposed between the color filter substrate and the array substrate, and the array substrate includes first and second electrodes to which different potentials are applied to drive the liquid crystals, and the liquid crystals has negative dielectric constant anisotropy.

5. The liquid crystal display device according to claim 4 , wherein when a drive voltage is applied between the first electrode, and the second electrode and a third electrode, molecules of the liquid crystals in a pixel region of the liquid crystal display device tilt to opposite directions symmetrically with respect to a straight line dividing the pixel region into two parts.

6. The liquid crystal display device according to claim 4 , wherein the first electrode and the second electrode are formed of a conductive metal-oxides that is transparent in a visible range.
