Abstract
A gate driving circuit provides a plurality of gate lines of a display panel with gate signals, the gate driving circuit including: a plurality of driving stages which correspond to the plurality of gate lines, respectively, and each of which outputs a carry signal and a gate signal for driving a corresponding gate line in response to a clock signal, an input signal, and a carry signal of a next stage; and a dummy driving stage which outputs a dummy carry signal in response to the clock signal, a carry signal of the last stage of the plurality of driving stages, and a carry signal output from any one of the plurality of driving stages.
