Abstract:
A display device includes a voltage generation circuit that generates a plurality of clock signals and a first driving voltage, a second driving voltage, and a third driving voltage. A gate driving circuit receives the generated clock signals and the first driving voltage, the second driving voltage, and the third driving voltage, and includes a plurality of driving stages each of which outputs a carry signal and a gate signal to a corresponding gate line among gate lines. The voltage generation circuit sets a voltage level of the third driving voltage based on a signal of a first node of at least one of the driving stages.
