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.

Abstract: Provided is a display device which includes a display panel, an anti-reflection layer disposed on the display panel, and a window disposed on the anti-reflection layer. The window includes a first portion including a first resin and disposed on the edge portion of the anti-reflection layer, and a second portion including a second resin and covering at least a portion of the first portion. The curing rate of the first resin is greater than the curing rate of the second resin. Thus, the display device may include the window having a small thickness and a smooth edge portion.
