Abstract: A gate driving circuit from which stable gate signals may be output by minimizing a leakage current of turned-off transistors in case that pull-down transistors output a gate signal and a carry signal of a low-level voltage. Some transistors in the gate driving circuit include two transistors in series to reduce leakage current in an off state, and capacitors are further included to reduce leakage current. Therefore voltages at nodes can be better controlled, and so that the output gate and carry voltages can be stably controlled.
