The application provides a shift register unit, a gate drive circuit, a display panel and a display device. The shift register unit comprises an input module configured to transmit an input signal to a first node; a first control module configured to transmit a first voltage signal to a second node and configured to transmit a second voltage signal to the second node; a second control module configured to transmit the first voltage signal to a third node and configured to transmit a first clock signal to the third node; an output module configured to transmit the first voltage signal to an output terminal and configured to transmit the second voltage signal to the output terminal; a first capacitor configured to stabilize the potential of the first node; a second capacitor configured to stabilize the potential of the second node; and a third capacitor configured to stabilize the potential of the third node. The shift register unit provided by the application can stabilize the output signal and improve the display effect of the display panel.

The invention discloses a gate drive circuit, a display panel and a display device. A level transmission module is used for outputting a level transmission signal, and an output module is used for outputting a gate control signal. A first output unit of the output module is communicated with a current path between a first output end and a first power supply end according to a second clock signal in a first time period, the cascade transmission module receives a starting signal according to the first clock signal in a second time period, and the first time period and the second time period are at least partially overlapped; the level transmission signal is used for sharing the load corresponding to the output end outputting the grid control signal, the requirement for the driving capacity of the output module is reduced, the layout size of the grid driving circuit is reduced, the potential of the first output end can be kept stable in the level change process of the level transmission signal, and the reliability of the grid driving circuit is improved. And the influence of residual charges, electric leakage and other factors on the gate control signal output by the first output end is reduced.
