Abstract
A gate drive circuit and a display panel are provided. A pull-up module and a pull-down module of the gate drive circuit output a constant-voltage high potential to a second node, a third node, and a n-th stage gate drive signal through a P-type thin film transistor and output constant-voltage low potential through a N-type thin film transistor to the second node, the third node, and an n-th gate drive signal, thereby improving the stability of the output signal of the thin film transistor connected to the gate drive circuit and the key node.
