    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.
