Abstract: 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.

Abstract: A display device includes a display module folded with respect to a folding axis extending in a direction and a window disposed on the display module and including a folding portion and a non-folding portion, the folding portion being folded with respect to the folding axis. The folding portion includes a first folding surface adjacent to the display module and a second folding surface opposite to the first folding surface and spaced apart from the first folding surface. Multiple first grooves may be defined in the first folding surface, multiple second grooves may be defined in the second folding surface, and a ratio of a Young's modulus of the folding portion to a Young's modulus of the non-folding portion may be in a range of about 30/70000 to about 2000/70000.
