A display device comprises a first base substrate (BS1); a liquid crystal layer (LC) disposed on the first base substrate; an overcoat layer (OC) disposed on the liquid crystal layer and comprising epoxy polymer; a color conversion layer (CFL) disposed on the overcoat layer; and a second base substrate (BS2) disposed on the color conversion layer.
The epoxy polymer is a polymer obtained by polymerizing 1 part to 50 parts by weight of a cardo-based binder resin; 1 part to 50 parts by weight of an epoxy-based monomer; and 1 part to 50 parts by weight of a bisphenol-based resin, with respect to 100 parts by weight of the epoxy polymer.
