摘要（英）：

The invention provides a shift register unit, a driving method, a gate driving circuit and a display device. The shift register unit comprises an input end, a gate drive signal output end, a first clock signal input end, a second clock signal input end, a third clock signal input end, an input module, a pull-up node control module, a pull-down node control module, a gate drive output module and acarry signal output module. The input module is respectively connected with the input end, the second clock signal input end and a pull-up node; the pull-up node control module is respectively connected with the pull-up node, a pull-down node, the first clock signal input end and a first voltage input end; the pull-down node control module is connected with the pull-down node, the pull-up node, the first clock signal input end, the first voltage input end and the second voltage input end. The shift register unit is beneficial to realizing a narrow frame and improving the stability of a gate driving signal.
