Patent ID: 7907237

Claim:
A color filter comprising a pattern formation substrate, the pattern formation substrate comprising: a transparent substrate; a partition pattern formed on the transparent substrate in an approximately orthogonal grid shape; and a coloring pattern of plural colors, provided in an opening partitioned off with the partition pattern, wherein the coloring pattern is formed in an approximately stripe shape in each one of the plural colors, the partition pattern is composed of an X-direction partition pattern provided in an approximately orthogonal direction to a longitudinal direction of the stripe of the coloring pattern and a Y-direction partition pattern provided in an approximately parallel direction to the longitudinal direction of the stripe of the coloring pattern, the X-direction partition pattern is composed of a first area in which an average film thickness is approximately the same as that of the Y-direction partition pattern and a second area in which an average film thickness is smaller than that of the Y-direction partition pattern, the second area is provided in an area close to a selected one of two Y-direction partition patterns adjacent to the X-direction partition pattern, and the selected one of the two Y-direction partition patterns alternates along the longitudinal direction of the stripe of the coloring pattern.
