Abstract
A photosensitive resin composition includes a binder resin, a black colorant, a photopolymerizable monomer, a photopolymerization initiator, and a solvent. The binder resin includes a first binder resin having a glass transition temperature of about −50° C. to about 150° C. and a second binder resin having a glass transition temperature of greater than about 150° C.
Claims14
A photosensitive resin composition, comprising:
- a binder resin;
- a black colorant;
- a photopolymerizable monomer;
- a photopolymerization initiator;
- and
- a solvent,
- wherein:
- the binder resin includes a first binder resin having a glass transition temperature of about −50° C. to about 150° C. and a second binder resin having a glass transition temperature of greater than about 150° C., wherein the second binder resin includes at least one selected from a polyamic acid polymer, a polyamic acid ester polymer, a polyhydroxyamide polymer, a polybenzoxazole polymer, and a polyamic acid-polyimide copolymer, provided that when the second binder resin includes a polyamic acid-polyimide copolymer, the polyamic acid-polyimide copolymer has a molecular weight of about 3,000 g/mol to about 10,000 g/mol, and
- the first binder resin is included in an amount of about 1 part by weight to about 900 parts by weight based on 100 parts by weight of the second binder resin.
