Abstract
A display device includes a substrate; a first electrode disposed on the substrate; a bank layer disposed on the substrate and including an opening exposing the first electrode; an emissive layer disposed on the first electrode exposed by the bank layer; a second electrode disposed on the bank layer and the emissive layer; an encapsulation layer disposed on the second electrode; and a touch layer disposed on the encapsulation layer, in which the encapsulation layer includes at least one inorganic film and at least one organic film, and in which the organic film contains organic molecules having an oval shape.
