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

摘要

Provided are: a photosensitive resin composition which has excellent adhesion to a base, high transmittance, high heat resistance and high sensitivity; a method for producing a cured film; a cured film; a liquid crystal display device; and an organic EL display device. A photosensitive resin composition which contains (A) a polybenzoxazole precursor containing a repeating unit represented by general formula (1), (B) a photoacid generator which generates an acid having a pKa of 4 or less, (C) a solvent and (D) a crosslinking agent having two or more crosslinkable groups which are reactive with a benzene ring and/or a phenolic hydroxyl group. In the formula, R1 and/or R2 is an acid-decomposable group. AA General formula (1)
