Patent ID: 8420296

Claim:
A photosensitive resin composition for a color filter protective layer, comprising: 0.1 to 30 wt % of (A) an alkali soluble resin comprising a cross-linkable alkali soluble resin having a repeating unit represented by the following Chemical Formula 1 and an alkali soluble resin that is different from the cross-linkable alkali-soluble resin having a repeating unit represented by Chemical Formula 1, wherein the photosensitive resin composition comprises 0.1 to 5 wt % of the cross-linkable alkali soluble resin having a repeating unit represented by the following Chemical Formula 1; 0.1 to 30 wt % of (B) a reactive unsaturated compound; 0.05 to 10 wt % of (C) a photopolymerization initiator; and (D) a solvent in a balance amount: wherein, in Chemical Formula 1, A 1 is a substituted or unsubstituted aromatic organic group or a substituted or unsubstituted alicyclic organic group, A 2 is represented by the following Chemical Formulas 2 or 3, R 1 and R 3 are independently substituted or unsubstituted alkylene, R 2 is hydrogen or substituted or unsubstituted alkyl, and R 4 is an oxygen atom or substituted or unsubstituted amine, wherein, in Chemical Formula 2, A 3 is a substituted or unsubstituted aromatic organic group or a substituted or unsubstituted alicyclic organic group, and wherein, in Chemical Formula 3, R 5 and R 6 are independently hydrogen, halogen, or substituted or unsubstituted alkyl.
