A shift register unit, a gate drive circuit and a display device. The shift register unit comprises: a bidirectional scanning pre-charging module, a pull-up module, a pull-down control module, a reset module and a pull-down module. A connection point between the bidirectional scanning pre-charging module and the pull-up module is a pull-up control node, and a connection point between the pull-down control module and the pull-down module is a pull-down control node. The pull-down control module is configured to conduct pull-down control according to signals input by a second clock signal end, a third clock signal end, and a fourth clock signal end. Bidirectional scanning is realized via the bidirectional scanning pre-charging module, and bidirectional pull-down can be realized by pulling down the potential of the pull-up control node and signals at signal output ends to a low level by the pull-down module. The power consumption of a circuit can be reduced by using four signal output terminals to drive. |
