Abstract
The present disclosure provides a gate driving circuit and a display panel. by the control of one of the fourth node, the output end of the second output module, and the first node of the shift register of the next stage, the voltage regulating module may utilize a low voltage signal to stabilize or reduce the gate voltage of the second transistor, so that the second transistor is stable or preferably in the cut-off state to reduce the leakage current. In this way, voltage level of the second gate driving signal can be maintained at a high voltage level or a pulse amplitude.
