Abstract

A gate driving circuit and a display panel are provided. A gate driving unit in the gate driving circuit includes a pull-up control module, a pull-up node, a pull-down control module, a pull-down node, and a pull-down module. The pull-up control module is electrically connected to the pull-up node. The pull-down control module is electrically connected to the pull-down node. The pull-down control module is electrically connected to a scanning signal input terminal of a previous one stage gate driving unit or a scanning signal input terminal of a previous two stage gate driving unit. The pull-down module is electrically connected to the pull-up node and the pull-down node.
