POSITIVE PHOTOSENSITIVE RESIN COMPOSITION, HARDENING FILM FORMATION METHOD, HARDENING FILM, LIQUID CRYSTAL DISPLAY DEVICE AND ORGANIC EL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a positive photosensitive resin composition which has high sensitivity and high thermal stability and with which a hardening film with low organic solvent swelling rate can be formed.

SOLUTION: A positive photosensitive resin composition includes (component A) resin including constitutional units expressed by the formula (1) and constitutional units having carboxy groups or phenol hydroxyl groups protected by acetal or ketal, (component B) acid generator, and (component C) solvent. In the formula (1), R1means a hydrogen atom or an alkyl group, L1means a bivalent connection group and L2means a trivalent hydrocarbon group.
