PHOTOSENSITIVE RESIN COMPOSITION FOR FORMING PATTERN, AND COLOR FILTER

摘要

PROBLEM TO BE SOLVED: To provide a photosensitive resin composition which causes very small heat shrinkage in heating after patternwise exposure and development and can accurately form a pattern, and a color filter which has columnar projections for setting the thickness of a liquid crystal layer and enables the production of a color liquid crystal display excellent in display quality. SOLUTION: The photosensitive resin composition for forming a pattern consists essentially of a monomer, a polymerization initiator and a resin binder whose weight average molecular weight is in the range of 20,000-70,000. The color filter has a colored layer comprising plural colors formed on a substrate in a prescribed pattern and transparent columnar projections formed in plural prescribed parts on the substrate. The columnar projections are formed by applying the photosensitive resin composition in such a way that it covers the colored layers and carrying out exposure through a photomask having prescribed openings, development and heating.
