Abstract

A display device includes a display module having a folding area and a non-folding area adjacent to the folding area. A glass substrate is disposed on the display module and comprises a first layer and a second layer disposed on the first layer. The second layer has a compressive strength that is higher than a compressive strength of the first layer. The first layer and the second layer of the glass substrate each include a folding portion overlapping the folding area and having a first thickness and a non-folding portion overlapping the non-folding area and having a second thickness greater than the first thickness. The second layer of the non-folding portion has a thickness that is greater than a thickness of the second layer of the folding portion.
