    Abstract: A gate driving circuit includes a plurality of stages to provide gate signals to gate lines of a display panel. At least one of the stages includes an input circuit receiving a carry signal from a previous stage. A first output circuit outputs a first clock signal as a gate signal. The second output circuit outputs the clock signal as a carry signal. The discharge hold circuit delivers the clock signal to a node based on the clock signal and discharges the node as a second voltage based on the carry signal. The pull down circuit discharges the gate signal as a first voltage based on a signal of the node and a succeeding carry signal from a succeeding stage and discharges another node and the carry signal as the second voltage. The switching circuit delivers the carry signal from the previous stage based on a second clock signal.
