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 flexible display device includes a protection member, a first adhesion member, a display member, a second adhesion member, and a window member. A thickness of the display member is less than a sum of thicknesses of the protection member and the window member. The display member includes a display panel layer, a touch sensing layer, and a reflection prevention layer integrated with each other to reduce a thickness of the flexible display device. The reduction in thickness enables the flexible display device to be bent with a relatively small radius of curvature, as well as to be repeatedly bent (or otherwise flexed) with reduced potential for delamination of the first and second adhesion members.

Abstract: A display apparatus has pixel area to emit light, a transmission area to transmit external light, and wirings including scan wiring, data wiring, and power wiring. The data and power wiring are adjacent to the pixel area and transmission area. An organic light-emitting device is in the pixel area. At least one of the data wiring or the power wiring includes first wiring and second wiring. The first wiring is adjacent to the pixel area and including a mother wiring having a first width. The second wiring includes a plurality of branched wirings that branch from the mother wiring. The branched wirings are adjacent to the transmission area, and a width of each of the branched wirings is less than the first width.
