It is something.

By making the longitudinal length of the inner spacer longer than the diagonal length of each pixel, it is possible to protect the colored area from damage caused by the spacer, prevent image deterioration, and improve reliability. .

［従来の技術］ 従来より、カラーフィルタを備えたカラー液晶表示素子

きるという点で、優れているとされている。Comparing these two methods, the vapor deposition method is said to be superior in that the colored layer can be formed thinner and the viewing angle of the liquid crystal can be increased.

き、信頼性を傷つける欠点があった。[Problems to be solved by application] However, since the 71-color layer formed by the vapor deposition method is made only of dyes, it is a relatively soft film, and even if it is covered with a hard protective film, the liquid crystal layer will not be affected. When an inner spacer is inserted to maintain a constant layer thickness, the protective film is broken and the colored layer is attacked by the liquid crystal, resulting in deterioration of image quality and damage to reliability.

With the goal.

This is a color liquid crystal display element f. In particular, in a preferred example of the present invention, the colored part has a layer thickness of J'7 greater than the layer thickness of the colored part.
By using a color filter in which individual pixels are formed by partitioning into a frame shape with a light-shielding part of −<, damage to the colored part caused by the spacer can be effectively prevented.

である。[Function] If a relatively hard film made of metal or the like is present under the protective layer 1, the protective film is almost never torn by the inner spacer. This invention is this! By focusing on the light-shielding layer of the color filter, we made the color filter's light-shielding layer the role of a pillar equivalent to a hard film, and
The dimensions of the inner spacer are set such that it is always blocked by the pillars, so that the colored layer is not affected in any way.

It is laminated on a liquid crystal layer 4 whose thickness is determined by a plurality of inner spacers 3 via a protective film 5, and is further sandwiched between a pair of substrates 8 each having an ITO 6 and a drive circuit 7. The 11 colored portions 2 are individually colored blue, red, or green and blue, and these three colored portions can be arranged in a mosaic shape or a striped shape. Also, among the cylindrical inner spacers 3 inserted to determine the layer thickness of the liquid crystal layer, the maximum length - "
The length B of the inner spacer 3 in the longitudinal direction is 1
The diagonal vj of one pixel of the colored part 2 is longer than the length A, and it is always blocked by the light shielding part l and cannot enter the pixel. The inner spacer 3 having the maximum length is made of a material such as glass fiber, and the thickness of the liquid crystal layer is determined by the diameter of the columnar shape. Usually, the thickness of the liquid crystal layer is approximately 10 JLm, and the pixel size is determined by the diameter of the cylinder. is sufficiently large, so that even if the length of the inner spacer 3 at its maximum length is the diagonal length of a pixel, it will not have any effect on image display. Particularly, preferably, the maximum length of the inner spacer 3 in the longitudinal direction is less than or equal to twice the diagonal length of the pixel, thereby substantially preventing the viewer from distinguishing the inner spacer 3 when the screen is displayed. be able to.
