Abstract
A gate driving circuit includes driving stages for providing gate signals to gate lines of a display panel. A k-th driving stage a k-th driving stage (k being equal to or greater than 2) among the driving stages includes a gate output unit configured to output a clock signal as a k-th gate signal in response to a voltage of a first node, a carry output unit configured to output the clock signal as a k-th carry signal in response to the voltage of the first node, a control unit configured to control a voltage level of the first node in response to a (k−1)th carry signal, a first discharge unit configured to discharge the k-th carry signal to a voltage level in response to the (k−1)th carry signal, and a second discharge unit configured to discharge the k-th carry signal to a voltage level in response to a discharge signal.
