PHOTOSENSITIVE RESIN COMPOSITION METHOD FOR MANUFACTURING CURED FILM CURED FILM LIQUID CRYSTAL DISPLAY DEVICE ORGANIC ELECTROLUMINESCENCE DISPLAY DEVICE AND TOUCH PANEL

摘要

A method for producing a cured film, a cured film, a liquid crystal display, an organic electroluminescence display, and a touch panel which are excellent in chemical resistance, light resistance and solvent solubility. The photosensitive resin composition contains a polybenzoxazole precursor, a photoacid generator that generates an acid having a pKa of 3 or less, or a quinone diazide compound and a solvent. The polybenzoxazole precursor is represented by the general formula (1) and The ratio of the repeating units represented by the general formula (1) to the repeating units represented by the general formula (2) in a molar ratio of 9: 1 (1) is 70% by mole or more based on the total repeating units, ~ 3: 7. Y ¹ represents a cyclic aliphatic group having 3 to 15 carbon atoms, and Y ² represents a linear or branched aliphatic group having 4 to 20 carbon atoms.
