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.

Method for manufactring display device having hole formed by multiple wet etching processes

A display device including a display panel and a supporter. The display panel includes a base layer that includes a plurality of stopper patterns and a support layer coupled to the plurality of stopper patterns. The supporter supports the plurality of stopper patterns and the support layer. The supporter includes a plurality of support blocks, each of which extends along the first direction and which are arrayed along the second direction. The plurality of support blocks include a first support block and a second support block spaced apart from each other in the second direction. The first support block includes a second portion overlapping the first stopper pattern among the plurality of stopper patterns when viewed in a plan view, and the second support block includes a first portion overlapping the first stopper pattern when viewed in a plan view.

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&#xb0; 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.

Reinforced window member and method of manufacturing the same

A method of fabricating strengthened glass includes strengthening a glass substrate to form a strengthened glass substrate including a first surface and a second surface opposite to the first surface, and slimming the strengthened glass substrate. The slimming may include slimming the first surface and not slimming the second surface, or slimming the first surface and the second surface differently from each other. Strengthened glass fabricated by this method of fabricating strengthened glass may be used in a bent display device.
