Abstract: A gate driving circuit includes a plurality of driving stages applying gate signals to gate lines of a display panel. Among the plurality of driving stages, a k-th (k being a natural number equal to or greater than 2) includes a first node, an output part that is connected to the first node and outputs a k-th gate signal in response to a voltage of the first node, a control part that controls an electric potential of the first node, an inverter part that outputs a k-th switching signal, and a pull-down part that receives a (k−1)th switching signal from a (k−1)th driving stage of the plurality of driving stages and lowers a voltage of the output part in response to the (k−1)th switching signal.
