Abstract
A gate driving circuit includes a plurality of stages which are connected to each other one after another and each stage of the plurality of stages outputs a gate voltage to a corresponding gate line of a plurality of gate lines in response to at least one clock signal. Each stage of the plurality of stages includes; a voltage output part which outputs the gate voltage, an output driving part which drives the voltage output part, a holding part which holds the gate line at an off-voltage, and a discharge part arranged at a first end of the gate line to discharge the gate line to the off-voltage in response to the gate voltage output from the voltage output part.
