Abstract
Disclosed herein is a display device. A first display panel displays first information. A second display panel is selectively placed in a superimposed position, in which the second display panel is superimposed on the first display panel, and in a non-superimposed position, in which the second display panel is not superimposed on the first display panel, and displays second information. A first touch panel is disposed on the first display panel. One or more second touch panels are disposed on the second display panel or disposed on the both side surfaces of the second display panel in pairs. A control unit applies driving voltage to at least one of the first and second display panels based on a signal detected from at least one of the first and second touch panels depending on any one of the superimposed position and the non-superimposed position of the first and second display panels.
