Abstract
A photoresist composition includes a binder resin combined with a black dye, a monomer, a photo-polymerization initiator and a remainder of a solvent.
Claims18
A photoresist composition, comprising:
- a binder resin bonded to a black dye;
- a monomer;
- a photo-polymerization initiator;
- and
- a remainder of a solvent, wherein the binder resin is represented by following Chemical Formula 4, wherein m, n, p and q represents mole fractions of corresponding repeating units, and sum of m, n, p and q is 100, and m, n, p and q are integers more than 0, and R1 represents —OCOCH═CHCH3, and R2 and R3 independently represent —NR5R6, —OR7, —CR8═CR9R10 or —OC(═O)CR11═CR12R13, and R5 to R13 independently represent a hydrogen atom or an alkyl group having carbon atoms of 1 to 5, and at least one hydrogen atoms of the alkyl group may be substituted with an alkyl group having carbon atoms of 1 to 20, an alkoxyl group having carbon atoms of 1 to 30, an aryl group having carbon atoms of 6 to 30 or an aryloxyl group having carbon atoms of 6 to 30,
