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.
