With this constitution, sufficient cell gaps can be realized and uniform cell gaps can be maintained in the screen and the problems of the degradation of the display quality caused by the variation of the cell gaps and the generation of foams at low temperature can be solved. The above described liquid crystal display element substrate and the liquid crystal display employing it are applied to the display screen of a personal computer, a word processor, an engineering work station, a navigation system, a liquid crystal television, a video tape player, etc. and are preferably used for a liquid crystal projection, etc..

SOLUTION: Blue, green and red picture elements 1-3 and fixed spacers 8 are arranged on a substrate 5 and an overcoat film 6 is formed to obtain the objective color filter. A black matrix 4 is preferably disposed among the picture elements 1-3. The overcoat film 6 is, e.g. an epoxy polymer film or an acrylic polymer film such as an epoxy film, an acrylic epoxy film or an acrylic film, a siloxane polymer film or a polyimide polymer film such as a polyimide film, a silicon-contg. polyimide film or a polyimidosiloxane film. The Young's modulus of the overcoat film 6 is >=2 GPa, preferably >=3 GPa, especially preferably >=4 GPa at 200 deg.C.

Abstract: PROBLEM TO BE SOLVED: To prevent a short circuit between a color filter and a counter substrate without limiting the design of the counter substrate by removing a transparent conductive film around the top of a spacer or removing the transparent conductive film on the spacer top and around the top to form a filter. SOLUTION: A black matrix 2 is formed by using a black paste on a nonalkali glass 1. Then a blue color layer 3 is formed to fill the openings in the black matrix 2 while a blue color layer 4 is simultaneously formed at the position where a spacer is to be formed on the black matrix 2. Similarly, a red color layer and a green color layer are formed in the openings 5, 7 and on the positions 6, 8 where the space is to be formed of the black matrix 2, respectively. Then a transparent protective layer 9 is formed and further a transparent conductive film 10 is laminated. Then the color filter substrate is set on a stage of a YAG laser illumination device, and the transparent conductive film 10 around the spacer is irradiated with laser light to produce the region 11 where the transparent conductive film 10 is removed.
