A display device. A back cover supports a rear surface of a display panel. A pair of support members are disposed on a left side and a right side of the back cover with respect to a central portion of the rear surface of the back cover. Outer ends of the pair of support members are fixed to the back cover. A curvature-changing unit is coupled to the central portion of the rear surface of the back cover to support the pair of support members in a lateral direction of the back cover and change a curvature of either the display panel or the back cover.
