Abstract: A display device can include a display panel, a cover shield disposed on a rear surface of the display panel, a curvature control member disposed on an inner side of the cover shield, and rotation members connected to ends of the curvature control member, respectively, and coupling the cover shield with the curvature control member. The curvature control member can be configured to rotate with the rotation members, Further, the cover shield is switched between a first state and a second state as the curvature control member rotates, and the cover shield is configured to be flat in the first state and is configured to be curved with a curvature in the second state. Therefore, the curvature of the display device is easily controlled by a simple structure and operation.
