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.
