There are provided a photosensitive resin composition having excellent chemical resistance, light resistance, and solubility in a solvent, a method for producing a cured film, a cured film, a liquid crystal display device, an organic electroluminescent display device, and a touch panel. The photosensitive resin composition contains a polybenzoxazole precursor, a photoacid generator which generates an acid having a pKa of 3 or less or a quinone diazide compound, and a solvent, in which the polybenzoxazole precursor contains a total of 70 mol % or more of a repeating unit represented by the following Formula (1) and a repeating unit represented by the following Formula (2) with respect to the total repeating units, and a ratio between the repeating unit represented by Formula (1) and the repeating unit represented by Formula (2) is 9:1 to 3:7 in a molar ratio. Y1 represents a cyclic aliphatic group having 3 to 15 carbon atoms, and Y2 represents a linear or branched aliphatic group having 4 to 20 carbon atoms.
