Abstract
Official abstract text for this publication.
A display device includes a first base substrate; a liquid crystal layer disposed on the first base substrate; an overcoat layer disposed on the liquid crystal layer and including epoxy polymer; a color conversion layer disposed on the overcoat layer; and a second base substrate 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.
