Abstract: A flexible display device includes a flexible display panel, a touch sensing layer on the flexible display panel, and a window on the touch sensing layer. The window may include an elastic portion and a plurality of rigid portions at a surface of the elastic portion and separated from each other. The elastic portion may be made of a soft material having elastic characteristics, and the rigid portion may be made of a hard material. The rigid portion may have a checkered pattern or a striped pattern at the surface of the elastic portion. The flexible display device may also include a barrier film at a surface of the flexible display panel. The barrier film may protect the flexible display panel and the touch sensing layer from external impacts.

Abstract: An organic light emitting display device includes a scan line, a data line, a power supply line, and a pixel. The scan line extends in one direction. The data line crosses the scan line. The power supply line crosses the scan line and the data line. The pixel is electrically coupled to the scan line, the data line, and the power supply line. The pixel includes an organic light emitting diode including a first electrode on a substrate, an organic layer on the first electrode, and a second electrode on the organic layer. The pixel further includes at least two domains configured to radiate light in directions different from each other.
