Abstract
Disclosed is a display device including: a display panel; a timing controller generating image data corresponding to an input image, and generating and outputting a first start signal, an on clock, and an off clock; a level shifter generating a second start signal in synchronization with the first start signal, generating gate clocks that swing to a predetermined voltage and have multiple phases, by using the on clock and the off clock, and outputting the generated gate clocks; a shift register including multiple stages connected to gate lines of the display panel, respectively, and outputting a scan signal sequentially to the gate lines by using the second start signal and the gate clocks; and a data driving circuit supplying a data voltage corresponding to the image data to data lines of the display panel in synchronization with the scan signal.
