Provided are a shift register unit and a gate driver circuit, which are configured to suppress output errors caused by the drifts in the threshold voltages and the interval existed in the operation of pulling the output terminal, and thus to enhance stability of the shift register unit. The shift register unit comprises: an input module, a first output module, a pull-down driving module, a pull-down module and a first output discharging unit. The pull-down driving module is connected to the first clock signal input terminal and the second clock signal input terminal, and configured to provide the first clock signal to a first pull-down node in response to the first clock signal, provide the second clock signal to a second pull-down node in response to the second clock signal, provide a first low voltage signal to the first pull-down node and the second pull-down node in response to the voltage signal at the pull-up node, provide the first low voltage signal to the second pull-down node in response to a voltage signal at the first pull-down node, and provide the first low voltage signal to the first pull-down node in response to a voltage signal at the second pull-down node. |
