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,
- A1 is a substituted or unsubstituted aromatic organic group or a substituted or unsubstituted alicyclic organic group,
- A2 is represented by the following Chemical Formulas 2 or 3,
- R1 and R3 are independently substituted or unsubstituted alkylene,
- R2 is hydrogen or substituted or unsubstituted alkyl, and
- R4 is an oxygen atom or substituted or unsubstituted amine,
- wherein, in Chemical Formula 2,
- A3 is a substituted or unsubstituted aromatic organic group or a substituted or unsubstituted alicyclic organic group, and
- wherein, in Chemical Formula 3,
- R5 and R6 are independently hydrogen, halogen, or substituted or unsubstituted alkyl.
