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 window includes: a folding part foldable around a virtual folding axis extending in a first direction, and first and second non-folding parts spaced apart from each other in a second direction perpendicular to the first direction with the folding part therebetween. A plurality of groove patterns extending in the first direction and arranged in the second direction are defined in the folding part. The folding part includes a first part adjacent to the folding axis, a third part adjacent to one of the first and second non-folding parts and a second part between the first part and the third part. widths of the first to third parts in the second direction are the same. A volume of the first part is greater than a volume of the second part, and the volume of the second part is greater than a volume of the third part.
