Abstract
A display device includes a display panel, a gate driving circuit including a plurality of stages, and a power supply circuit outputting a clock signal, a clock-bar signal, a first discharge voltage, and a second discharge voltage. Each of stages includes a charge part that charges a clock signal having a first high voltage to a charge node, an output part that charges the first high voltage to an output node in response to a first node voltage of the charge node and outputs a second node voltage of the output node to a gate signal, a first discharge part that discharges the second node voltage to a first discharge voltage in response to the clock-bar signal having a second high voltage, and a second discharge part that discharges the first node voltage to a second discharge voltage in response to the clock-bar signal having the second high voltage.
