Abstract:
1. A photosensitive resin composition for forming a microlens, the photosensitive resin composition comprising: a component (A); a component (B); a component (C); and a solvent, wherein the component (A) is a copolymer having a maleimide structural unit of formula (1) below, a vinyl ether structural unit of formula (2) below, and at least one of the three structural units of formula (3), formula (4), and formula (5) below, the component (B) is a photosensitizer, and the component (C) is a cross-linking agent (where X is a C 1-20 hydrocarbon group; Y is a C 1-5 alkyl group, a C 5-6 cycloalkyl group, a phenyl group, or a benzyl group; and Z is a phenyl group, a naphthyl group, an anthracenyl group, a biphenylyl group, or a C 1-8 alkoxy group, provided that the group represented by X optionally has an ether bond or a cyclic structure; part of or all of hydrogen atoms of the group represented by Y are optionally substituted with a halogen atom, a carboxy group, a hydroxy group, an amino group, or a nitro group; and part of or all of hydrogen atoms of a phenyl group, a naphthyl group, an anthracenyl group, or a biphenylyl group represented by Z are optionally substituted with a C 1-10 alkyl group, a C 5-6 cycloalkyl group, a halogen atom, a carboxy group, a hydroxy group, an amino group, or a nitro group).
