Abstract: The present application provides a shift register unit as well as a gate drive circuit and a display device using it. The shift register unit comprises an input module, an NAND gate module, an inverter module, a pull-up module and a pull-down module. The input module receives an input signal and a first clock signal, and transfers the input signal to a first input end of the NAND gate module and the pull-down module under the control of the first clock signal. A second input end of the NAND gate module receives a second clock signal input, and an output end thereof connects the inverter module. An output end of the inverter module connects the pull-up module. The pull-up module pulls up the output signal to a high level based on the output of the inverter module. The pull-down module pulls down the output signal to a low level under the control of the received input signal and the second clock signal. By arranging the inverter module, it can be ensured that no floating point exists at the gate of the output transistor so that it is not affected by leak point, thereby maintaining stable signal output and improving stable output ability of the shift register.
