Abstract: Disclosed are a curved display device and a driving method thereof. The curved display device includes a flexible display panel, a bottom cover serving as a rear surface casing for the display panel, and at least one curvature control unit disposed on a rear surface of the bottom cover to control curvature of the bottom cover by applying tensile force to the rear surface of the bottom cover in a longitudinal direction of the bottom cover. The bottom cover is formed of a corrugated board including an intermediate layer provided with ridges, a first cover layer serving as a coating for an upper surface of the intermediate layer, and a second cover layer serving as a coating for a lower surface of the intermediate layer. The first cover layer has an opening configured to expose the intermediate layer to correspond to the curvature control unit.
