摘要： A window includes a folding portion foldable with respect to an imaginary folding axis extending in a first direction, a first non-folding portion, and a second non-folding portion spaced apart from the first non-folding portion in a second direction perpendicular to the first direction with the folding portion interposed therebetween. The folding portion includes a base portion and a plurality of protrusion portions disposed on the base portion and spaced apart from each other in the second direction. A width, in the first direction, of the folding portion is smaller than a width, in the first direction, of each of the first non-folding portion and the second non-folding portion.

摘要： A display device includes a folding area foldable about a folding axis and a non-folding area proximate to the folding area. The display device includes a display module that displays an image and a glass window that is disposed over the display module that includes a patterned glass. The patterned glass includes a pattern portion including a groove pattern provided on one surface of the patterned glass to correspond to the folding area and a non-pattern portion disposed adjacent to the pattern portion to correspond to the folding area. The pattern portion has a thickness that is smaller than or equal to one-half a thickness of the non-pattern portion.
