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 panel, and a pattern glass disposed on the display panel and including a first non-pattern portion, a pattern portion, and a second non-pattern portion, which are arranged in a first direction. The pattern portion includes a plurality of patterns having a shape and arranged in the first direction and a second direction intersecting the first direction, and openings defined through the pattern glass between the plurality of patterns adjacent to each other. Each of the openings has a symmetrical shape with respect to a third direction intersecting a plane defined by the first and second directions based on a symmetry axis extending in the second direction. The symmetry axis passes through a midpoint of a thickness of the pattern glass.
