Abstract

A color filter substrate is provided with a transparent substrate and color filters of three colors with a bored part provided at every pixel on the transparent substrate. Color filters neighboring to each other in one direction are connected to each other. A thin film transistor is to oppose to the bored part. Data lines are to be aligned along said one direction.

Claims (9)

1. A color filter substrate of a liquid crystal display panel constituted by said color filter substrate and a TFT substrate and a liquid crystal provided between them, comprising:

a transparent substrate;

color filters of three colors, at least two of which have an opening provided at every pixel on said transparent substrate, said openings being opposed to and vertically aligned with a thin film transistor formed on said TFT substrate, said color filters of three colors neighboring each other in one direction being connected to and aligned with each other in a plane of the color filter substrate, and data lines being aligned along said one direction; and

color filters located in said openings with a material identical to any one of said color filters of three colors and different from the color of the color filter in which the opening is provided.

2. An active matrix type liquid crystal display comprising a color filter substrate according to claim 1 .

3. A color filter substrate of a liquid crystal display panel constituted by said color filter substrate and a TFT substrate and a liquid crystal provided between them, comprising:

a transparent substrate;

color filters of three colors, at least two which having a cutout provided at every pixel on said transparent substrate, said cutouts being opposed to and vertically aligned with a thin film transistor formed on said TFT substrate, said color filters of three colors neighboring each other in one direction being connected to and aligned with each other in a plane of the color filter substrate, and data lines being aligned along said one direction; and

color filters located in said cutouts with a material identical to any one of said color filters of three colors and different from the color of the color filter in which the cutout is provided.
