The invention provides a shifting register unit, a gate drive circuit and a driving method thereof, and a display device. The shifting register unit includes two transmission gate modules, four AND gate modules and two capacitor modules, and has a pulse signal input end, four pulse signal output ends and a plurality of clock signal input ends. The shifting register unit provided by the invention can enable the corresponding gate drive circuit to substantially reduce a layout area that needs to be occupied compared with a gate drive circuit in the prior art, thereby distributing to side narrowing of the corresponding display device.
