PROBLEM TO BE SOLVED: To provide a color filter formed, using an alkali developable photosensitive resin composition superior in long-term shelf stability, high sensitivity, developing speed and resolution and having a formed pixel part or black matrix superior in heat resistance, adhesion to a substrate, hardness, solvent and alkali resistances in a coating film after being cured by irradiation with light. SOLUTION: The color filter is formed using the photosensitive resin composition containing at least an α,β-unsaturted group containing carboxylic acid compound, having an acidic value of 20-150 (expressed in terms of solid), obtained by adding a polybasic carboxylic acid anhydride of formula (2) to a polyol compound of formula (1) having α,β-unsaturated groups, a photopolymerizable monomer and a photopolymerization initiator. |
