Abstract
The present application discloses a gate drive circuit and a display device. The gate drive circuit includes a plurality of cascaded gate drive units, in which one of the gate drive units includes a first layout, an input module and a pull-up module. By receiving a potential changeable signal by the gate of a first transistor or the gate of a second thin-film transistor, it can alleviate or avoid current leakage caused when a first node keeps at a same voltage level for a long time, thereby improving the stability of the potential of the first node.
