Abstract
A GOA circuit and a display panel are provided. The GOA circuit includes a first pull-down module for pulling down a voltage level of a current-stage gate driving signal, a second pull-down module for pulling down a voltage level of the first node, a third pull-down module for pulling down a voltage level of the second node, and a fourth pull-down module for pulling down the voltage level of the current-stage gate driving signal. The GOA circuit raises the effect of pulling down the current-stage gate driving signal.
