Abstract: Red pixels (R), blue pixels (B) and green pixels (G) are formed in parallel. First columnar spacers 10 and second columnar spacers 20 are formed on a first substrate. The distance between the first substrate and a second substrate in a normal state is determined by the first columnar spacers 10. The diameter of a light blocking film corresponding to each first columnar spacer 10 is greater than the diameter of a light blocking film corresponding to each second columnar spacer 20. The first columnar spacer 10 is not formed at a boundary between a green pixel (G) and a red pixel (R) or a boundary between a green pixel (G) and a blue pixel (B). The second columnar spacer 20 is formed at a boundary between pixels irrespective of the pixel color. Thus, appropriate color balance can be attained with ease without having a drop in the luminance.

Abstract: An object of this invention is to increase the number of liquid crystal display panels obtained from a mother substrate. There is provided a liquid crystal display device including a TFT substrate and a counter substrate bonded together by a seal portion formed along the periphery of the counter substrate, the TFT substrate having a terminal area formed in a portion thereof not opposed to the counter substrate. The TFT substrate has a bank-like organic passivation film formed along the edge of the terminal area. A stepped part is formed on the organic passivation film. The film thickness of the organic passivation film on the edge side of the stepped part is greater than the film thickness inside the stepped part.

Abstract: A liquid crystal display device includes a thin film transistor substrate, a counter substrate that faces the thin film transistor substrate, a liquid crystal composition that is arranged between the thin film transistor substrate and the counter substrate, an oriented film that arranges orientation of the liquid crystal composition contacting with the thin film transistor substrate, a seal material that seals the liquid crystal composition between the two substrates, and a driver circuit. The driver circuit has a light transmission area that is formed inside of the driver circuit, and is higher in light transmittance than an area in which a non-transparent conductive film forming the driver circuit is formed, and a high sealing property area in which the seal material and an insulating film come into direct contact with each other between the light transmission area and an outer edge of the thin film transistor substrate.
