Abstract
A gate drive circuit and a display panel. The gate drive circuit includes multi-stage cascaded gate drive units. The gate drive units each include a pull-up control module, an output module, a pull-down module, a pull-down maintain module, a first reference low-level signal input terminal, a second reference low-level signal input terminal, and a pull-up node located in a line between the pull-up control module and the output module. The pull-up control module includes a pull-up control transistor that is electrically connected to the pull-up node and configured to pull a potential of the pull-up node up. The output module includes a scan signal output transistor that is electrically connected to the pull-up node and configured to output a present-stage scan signal under control of the potential of the pull-up node.
