COLOR FILTER AND MANUFACTURE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a color filter having a high display grade by embedding a light shielding layer in a recessed pattern on a transparent base board, and laminating a photosensitive coloring resin composition forming a coloring pattern. SOLUTION: A photosensitive A color resin layer 40A is applied on a transparent base board 10 on which a recessed pattern 12 is arranged. It is exposed and developed on the A color resin layer 40A through a photosensitive A color resin photomask 32 by an ultraviolet ray(UV) or the like, and a photosensitive A color resin layer 40A pattern is obtained. At this time, the A color resin layer 40A remains on the recessed pattern 12. These are heated and baked, and an A color resin is thermally hardened. Then, a similar process is repeated on a photosensitive B color resin layer 40B and a photosensitive C color resin layer 40C. A coloring resin composition laminated by the color number of formed coloring patterns, is formed on the recessed pattern 12, and becomes black to the transmitted light, and becomes a light shielding layer.
