A gate driving circuit includes a plurality of shift registers coupled in serial. An nth shift register includes a driving circuit, a pull-up circuit, a first auxiliary voltage regulator circuit, and a second auxiliary voltage regulator circuit. The driving circuit is electrically coupled to an output node and a first node. The pull-up circuit is electrically coupled to the driving circuit. The first auxiliary voltage regulator circuit is electrically coupled to the pull-up circuit, and configured to receive a control signal, and keep an nth first voltage to a second low voltage. The second auxiliary voltage regulator circuit is electrically coupled to the pull-up circuit, and configured to receive the control signal, and keep the nth first voltage to the second low voltage.
