Abstract: A window member includes a first member and a second member, and is divided into a transmission area and a light blocking area. The first member includes a first base member, and a first decoration member on a portion of a surface of the first base member. The second member includes a second base member, and a second decoration member on a portion of a surface of the second base member configured to define a boundary line between the transmission area and the light blocking area. The second base member includes a first area on which the second decoration member is disposed and corresponding to a portion of the light blocking area; a second area corresponding to the transmission area, and a third area corresponding to the remaining portion of the light blocking area. The first decoration member overlaps with the third area and partially overlaps with the first area.

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.
