Abstract: A display device according to an exemplary embodiment of the present disclosure includes a display panel having a display area, a back cover disposed on a rear surface of the display panel, a first roller which winds or unwinds the back cover and the display panel, and a second roller which is disposed above the first roller to move in a vertical direction, the back cover and the display panel being overlaid on the second roller. The emission area is flexibly adjusted during the partial view so as to suppress a burn-in issue and improve the lifespan of the display device.

Abstract: Display devices and methods of manufacturing display devices are provided in which a sealing layer is provided on a metal layer, and the metal layer may be removed thereby facilitating removal of the sealing layer, for example, during a repair process. A display device includes a first substrate and a display assembly on the first substrate. The display assembly includes a plurality of sub-pixels, and a portion of the first substrate extends laterally beyond a periphery of the display assembly. A protective layer is provided on the portion of the first substrate that extends laterally beyond the periphery of the display assembly, and a sealing layer is disposed on the protective layer.
