Abstract

The invention provides an alkali development-type photosensitive resin composition and a color alkali development-type photosensitive resin composition that are excellent in sensitivity, resolution, transparency, developability, adhesion, alkali resistance and the like and can form a fine pattern having a good shape with high accuracy. An alkali development-type photosensitive resin composition comprising a binder resin, a photopolymerization initiator, and a solvent, characterized in that the binder resin is a photopolymerizable unsaturated compound prepared by reacting an epoxy adduct with a specific proportion of a polybasic acid anhydride (D). The epoxy adduct has a structure prepared by adding, to a polyfunctional epoxy resin (A), an unsaturated monobasic acid (B), and a cyclic terpene structure skeleton-containing phenol compound (C-1), prepared by adding a specific proportion of phenol or an alkylphenol compound to a cyclic terpene compound, and / or an aliphatic alkylphenol compound (C-2).

Description

technical field [0001] The present invention relates to an alkali-developing photosensitive resin composition suitable for producing color filters used in color liquid crystal display devices, image sensors, etc., and substrates with protrusions for controlling alignment of liquid crystal divisions. The substrate with the liquid crystal division alignment control protrusion and the color filter, and the liquid crystal display device having the substrate with the liquid crystal division alignment control protrusion or the color filter. Background technique [0002] Alkali-developing photosensitive resin compositions containing an alkali-soluble binder resin having an ethylenically unsaturated bond, a photopolymerization initiator, and a solvent are widely used in the manufacture of color filters that are important elements of color liquid crystal display devices, image sensors, and the like. device etc. In recent years, with the development of thinner, thinner, and higher pe...
