Abstract
A photosensitive composition including a quantum dot dispersion, a photopolymerizable monomer having a carbon-carbon double bond, and a photoinitiator, wherein the quantum dot dispersion includes an acid group-containing polymer and a plurality of quantum dots dispersed in the acid group-containing polymer, and wherein the acid group-containing polymer includes a copolymer of a monomer combination including a first monomer having a carboxylic acid group or a phosphonic acid group and a carbon-carbon double bond and a second monomer having a carbon-carbon double bond and a hydrophobic group and not having a carboxylic acid group and a phosphonic acid group.
