Claim Text:
1. A negative photosensitive resin composition, comprising: an alkali-soluble resin (A); a photoacid generator (B); a basic compound (C); a cross-linking agent (D); and a solvent (E), wherein the alkali-soluble resin (A) comprises an acrylate resin (A-1) and a novolac resin (A-2); the acrylate resin (A-1) being synthesized by polymerizing a monomer for polymerization, the monomer for polymerization comprising an unsaturated carboxylic acid or unsaturated carboxylic acid anhydride monomer (a-1-1) and a monomer (a-1-2), the monomer (a-1-2) comprising a compound (a-1-2-1) with a tricyclodecane or dicyclopentadiene structure and a compound (a-1-2-2) represented by formula (1), wherein in formula (1), in is an integer of 0 to 2, and wherein based on 100 parts by weight of the monomer used in the polymerization of the acrylate resin (A-1), a used amount of the compound (a-1-2-1) with a tricyclodecane or dicyclopentadiene structure and the compound (a-1-2-2) represented by formula (1) is 10 to 60 parts by weight; the novolac resin (A-2) being synthesized by polymerizing an aldehyde compound with an aromatic hydroxy compound, the aromatic hydroxy compound comprising a xylenol compound, and wherein based on a used amount of the aromatic hydroxy compound used in the polymerization of the novolac resin (A-2) being 1 mol, a used amount of the xylenol compound is 0.1 mol to 0.5 mol.
