Abstract
A display device for displaying display data including a display panel; a driving circuit which generates a gray-scale voltage corresponding to the display data and outputs the gray-scale voltage to the display panel; a scan driver which scans a line on the display panel to which the gray-scale voltage is output; and a control circuit which outputs the display data to the driving circuit and outputs a display control signal to the scan driver. A gray-scale display characteristic of the display data is changeable between a first state in which a difference in a brightness of the display panel between two adjacent display data values becomes smaller as a display data gray-scale increases, and a second state in which the difference in the brightness of the display panel between two adjacent display data values becomes larger as the display data gray-scale increases.
