Abstract
A display device includes a display panel in which a plurality of pixels is defined, a back cover disposed on a rear surface of the display panel, a roller which is connected to the back cover to wind or unwind the back cover and the display panel, and a protective sheet which is disposed on a rear surface of the back cover and has a relatively small tensile strength in a rolling direction of the roller to reduce the stress generated during rolling and improve the lateral rigidity of the display unit.
