PURPOSE: A positive type photosensitive resin composition, a photosensitive resin film using the same, a displaying device including the photosensitive resin film are provided to secure superior contrast ratio to the photosensitive resin film by preventing the leakage of light through pixels. CONSTITUTION: A positive type photosensitive resin composition includes an alkali soluble resin, a photosensitive diazoquinone compound, a phenol compound, and a solvent. The phenol compound becomes opaque in the process of curing. The alkali soluble resin includes a polybenzoxazole precursor with a repeating unit represented by chemical formula 1, poly(amic acid) with a repeating unit represented by chemical formula 2, polyimide with a repeating unit represented by chemical formula 3, or the combination of the same. In chemical formula 1, X1 is identical or different in each repeating unit and respectively a substituted or non-substituted C6 to C30 aromatic organic group; and Y1 is identical or different in each repeating unit and respectively a substituted or non-substituted C6 to C30 aromatic organic group, a substituted or non-substituted divalent to hexavalent C1 to C30 aliphatic organic group, or a substituted or non-substituted divalent to hexavalent C3 to C30 aliphatic organic group. The phenol compound includes a compound represented by chemical formula 15. |
