Abstract: A display device includes a display element layer including a first electrode layer, a light-emitting layer disposed on the first electrode layer, and a second electrode layer disposed on the light-emitting layer, a capping layer disposed on the second electrode layer, a protective layer disposed on the capping layer and covering a portion of the second electrode layer exposed by the capping layer, an optical compensation layer disposed on the protective layer, and an encapsulation layer disposed on the optical compensation layer. The refractive index of the optical compensation layer is lower than that of the protective layer.

Abstract: A method of manufacturing a window member includes performing a first reinforcement operation including performing a first ion-exchange treatment on an initial window member. The first ion-exchange treatment includes applying ion salts at a temperature equal to or greater than a first temperature of about 500° C. A stress relief operation includes performing a heat treatment and/or a salt treatment on the initial window member to which the first reinforcement operation is performed. A second reinforcement operation includes performing a second ion-exchange treatment on the initial window member to which the stress relief operation is performed.
