Abstract

The present invention discloses a photosensitive resin composition for an insulating film of a display device including (A) an alkali soluble resin; (B) a photosensitive diazoquinone compound; (C) a color material having a maximum absorption wavelength of 400 to 550 nm; and (D) a solvent, an insulation film using the same, and a display device including the insulation film.

First claim

The invention claimed is:

1. A photosensitive resin composition for an insulating film of a display device, comprising:
(A) an alkali soluble resin, wherein the alkali soluble resin (A) is a polybenzoxazole precursor, polyamic acid, polyimide, or a combination thereof;
(B) a photosensitive diazoquinone compound;
(C) a color material having a maximum absorption wavelength of 400 to 550 nm; and
(D) a solvent,
wherein the color material includes a compound represented by the following Chemical Formula 10, a compound represented by the following Chemical Formula 11, or a combination thereof:

wherein in the above Chemical Formula 10, R 1 to R 6 are independently selected from hydrogen, a halogen, a substituted or unsubstituted C1 to C20 alkyl group, a substituted or unsubstituted C3 to C20 cycloalkyl group, a substituted or unsubstituted C6 to C30 aryl group, and a substituted or unsubstituted C6 to C30 heteroaryl group;

wherein in the above Chemical Formula 11,
R 11 to R 14 and R 20 to R 39 are each independently selected from a hydrogen atom, a halogen atom, a hydroxy group, a sulfonic acid group (—SO 3 H), a nitro group, a carboxyl group, a cyan group, a substituted or unsubstituted C1 to C20 alkyl group, a substituted or unsubstituted C3 to C20 cycloalkyl group, a substituted or unsubstituted C1 to C20 heteroalkyl group, a substituted or unsubstituted C3 to C20 heterocycloalkyl group, a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C6 to C30 heteroaryl group, and a combination thereof, and
Z is selected from two hydrogen atoms, a divalent metal atom, a divalent metal oxide, a divalent metal hydroxide, and a divalent metal chloride.

2. The photosensitive resin composition of claim 1 comprising:
5 to 100 parts by weight of the photosensitive diazoquinone compound (B);
1 to 30 parts by weight of the color material (C); and
100 to 900 parts by weight of the solvent (D)
based on 100 parts by weight of the alkali soluble resin (A).

3. The photosensitive resin composition of claim 1 , further comprising a silane compound.

4. The photosensitive resin composition of claim 1 , further comprising a phenol compound.

5. An insulation film of a display device manufactured using the photosensitive resin compositions according to claim 1 .

6. A display device including the insulation film according to claim 5 .
