Claim:
1. A display device, comprising: a display panel having a curvature radius; a plurality of region control parts attached to respective regions of the display panel configured to control the curvature radius of the display panel; a driver driving the display panel; a timing controller controlling the driver; an image processor supplying an image signal to the timing controller; and an image corrector automatically compression-correcting or expansion-correcting the image signal in response to a change to the curvature radius of the display panel such that an edge portion of the image signal concavely recedes or convexly protrudes, wherein the image corrector: receives, from the plurality of region control parts, curvature information representing a current curvature radius of the display panel; retrieves, from a lookup table, a curvature coefficient corresponding to the current curvature radius of the panel; and
