PHOTOSENSITIVE RESIN COMPOSITION, METHOD FOR PRODUCING CURED FILM, CURED FILM, ORGANIC EL DISPLAY DEVICE, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

Provided is a photosensitive resin composition which exhibits excellent adhesion during development, while maintaining high sensitivity, transparency and chemical resistance. A photosensitive resin composition which contains: (1) a polymer that has (a1) a constituent unit having a group wherein an acid group is protected with an acid-decomposable group and (a2) a constituent unit having a crosslinkable group, and (2) (a1) a polymer that has a constituent unit having a group wherein an acid group is protected with an acid-decomposable group, and/or (a2) a polymer which has a constituent unit having a crosslinkable group; (S) a polymer that has a weight average molecular weight of 1,000-50,000 and a constituent unit containing a carboxyl group; (B) a photoacid generator; and (C) a solvent. The polymer (S) has a value represented by formula (1) of 50-3,000. Formula (1): [solid acid value (unit: mgKOH/g) of polymer (S)] × [content ratio (unit: mass%) of polymer (S) relative to total solid content in photosensitive resin composition]
