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

摘要

PROBLEM TO BE SOLVED: To provide a positive photosensitive resin composition capable of giving a cured film that has having high sensitivity, high durability against a stripping solution or NMP (N-methyl pyrrolidone), good adhesiveness to a transparent electrode film or metal, excellent dry etching durability and that hardly induces a display failure in a display device.SOLUTION: The positive photosensitive resin composition comprises: (component A) a polymer component including a polymer satisfying at least one of the following conditions (1) and (2); (component C) a photoacid generator; and (component D) a solvent. (1) A polymer having (a1) a structural unit having a group in which an acid group is protected by an acid decomposable group and (a2) a structural unit having a crosslinking group; and (2) a polymer having (a1) a structural unit having a group in which an acid group is protected by an acid decomposable group and a polymer having (a2) a structural unit having a crosslinking group.
