Disclosed is a gate drive circuit. The circuit includes multiple stages of gate drive units, and a gate drive unit in each stage includes a pull-up control module which outputs a pull-up control signal based on a previous stage of gate drive signal, a first pull-up module connected to the pull-up control module, a boost module connected to the first pull-up module, a second pull-up module connected to the first pull-up module, and a pull-down module connected to the first pull-up module and the second pull-up module.
