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: A method for manufacturing a display device includes forming a first hole that extends into a substrate, through a first wet etching process using a first etchant and forming a second hole that extends from the first hole further into the substrate, through a second wet etching process using a second etchant. The second etchant has a pH different from a pH of the first etchant.

Abstract: Disclosed is a display device which includes a display module and a window. The window includes a transmission region and a bezel region adjacent to the transmission region, and the window is directly disposed on the display module. The window includes a resin material. The display device includes a light blocking pattern that overlaps the bezel region. An outside surface of the window protrudes further outward compared to an outside surface of the display module, and a front surface of the window includes a curved portion. The curved portion curves toward a rear surface of the window as a distance from the transmission region increases.

Abstract: A cover window is disclosed. The cover window may include a first surface, a second surface opposite the first surface, a first polishing surface extending from an end of the first surface along a first direction, the first polishing surface having a first inclination angle, and a second polishing surface extending from an end of the second surface along a second direction, the second polishing surface having a second inclination angle. The first polishing surface and the second polishing surface may be asymmetric with respect to a center plane, the center plane passing through a center of the cover window and in parallel with the first surface.
