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

摘要

PURPOSE: A positive type photosensitive resin composition is provided to have high sensitivity, high tolerance to a separation liquid and NMP, and to have excellent transparent electrode film and metal. CONSTITUTION: A positive type photosensitive resin composition: contains a structure unit indicated in chemical formula a1-1 which has an acetal or ketal residue; and a copolymer with a pre-crosslinkable group. In chemical formula a1-1, R1 is a hydrogen atom or methyl group, R2 is a C1-6 alkyl group, R3 is a C1-6 alkyl group or C4-7 cycloalkyl group, and R2 and R3 can form a ring by being connected to each other.
