Abstract: A display device includes a display panel having a first non-folding region, a folding region, and a second non-folding region consecutively arranged in a first direction. The folding region is adjacent to the first and second non-folding regions and is foldable about a folding axis. A lower substrate is disposed under the display panel. The lower substrate includes a spacing portion and a pattern portion. The spacing portion overlaps the folding region on a plane. The pattern portion is spaced apart from the display panel by the spacing portion in a thickness direction of the display device. The pattern portion includes a plurality of holes.

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.
