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.

Abstract: A display device includes a display panel; a back cover supporting the display panel on a rear surface of the display panel; a roller disposed on a rear surface of the back cover, wherein the display panel and the back cover are wound around or unwound from the roller; a flexible film electrically connected to a pad area of the display panel; and a sealing layer disposed to cover an end of the flexible film. At least some of elements of the display panel including a substrate may be extended beyond the sealing layer. Accordingly, it is possible to prevent cracks in the display panel due to the pressing by the cover plate and the overflow of the sealant, thereby solving the issues of driving failure and reliability of the display panel.
