Abstract: The display device includes a display panel including an active area and a non-active area; and a polarization plate on the display panel, the polarization plate including a polarization layer. The polarization layer includes a first pattern corresponding to the active area and a second pattern corresponding to the non-active area, and the second pattern is spaced apart from the first pattern. Thus, it is possible to delay moisture absorption of a polarization layer.

Abstract: A display device includes a display panel in which a plurality of pixels is defined. The display device further includes a back cover configured to be rolled together with the display panel. The display device further includes a roller winding or unwinding the back cover and the display panel, and including a flat surface and a curved surface. The display device further includes a buffer member covering at least a part of the back cover fixed to the roller, and having a width smaller than a width of the display panel. Therefore, the display panel is wound around the roller with a gentle slope, and non-display areas on both side portions of the display panel are wound around a roller with a space by the buffer member. Accordingly, a stress applied to the display panel and a crack may be reduced to improve reliability of the display device.
