Abstract: The present application provides a gate driving circuit and a display panel. The gate driving circuit includes a plurality of cascaded gate driving units, where each of the plurality of cascaded gate driving units includes a pull-up control module, an inversion module and a feedback module. The potential of the pull-up node is stepwise increased by the pull-up control module, so that the feedback module can be controlled to be turned off by the inversion module when the potential of the pull-up node is lower, thereby improving a phenomenon of leakage of the pull-up node through the feedback module.
