Abstract

A photosensitive resin composition includes: (A) a binder resin; (B) a photopolymerizable monomer; (C) a photopolymerization initiator; (D) a quantum dot surface-modified with a compound having a thiol group at one terminal end and an alkoxy group, a cycloalkyl group, a carboxyl group, or a hydroxy group at the other terminal end; and (E) a solvent. A curable composition includes: (A') a resin; (B′) a quantum dot surface-modified with a compound represented by Chemical Formula 1 or Chemical Formula 2; and (C′) a solvent. A method of manufacturing the surface-modified quantum dot, and a color filter manufactured using the photosensitive resin composition or the curable composition are also disclosed.
