摘要

PROBLEM TO BE SOLVED: To provide a photosensitive resin composition that can give a fine and good spacer shape excellent in spacer characteristics such as an elastic modulus, a deformation amount and an elastic recovery rate while maintaining light-shielding property and insulating property.SOLUTION: The present invention relates to a photosensitive resin for a light-shielding film having a spacer function. The photosensitive resin composition of the present invention comprises, as essential components: (A) a polymerizable unsaturated group-containing alkali-soluble resin obtained by allowing (a) a dicarboxylic acid or tricarboxylic acid or an acid anhydride thereof and (b) a tetracarboxylic acid or an acid dianhydride thereof to react with a reaction product of an unsaturated group-containing monocarboxylic acid and an epoxy compound having two glycidyl ether groups derived from bisphenol; (B) a photopolymerizable monomer having at least one ethylenically unsaturated bond; (C) a photopolymerization initiator; (D) at least one light-shielding component selected from the group consisting of a black organic pigment, a mixture color organic pigment and a light-shielding material; and (E) a solvent.SELECTED DRAWING: None
