Abstract
A photosensitive composition including: a plurality of quantum dots, wherein the quantum dot includes an organic ligand with a hydrophobic moiety bound to a surface of the quantum dot; a binder; a photopolymerizable monomer having a carbon-carbon double bond; a photoinitiator; and a solvent, wherein the binder includes a multiple aromatic ring-containing polymer including a main chain including a carboxylic acid group and a backbone structure incorporated in the main chain, wherein the backbone structure includes a quaternary carbon atom, which is a part of a cyclic group, and two aromatic rings bound to the quaternary carbon atom, and wherein the plurality of quantum dots are dispersed in the binder.
