Abstract

A shift register and a gate driver circuit are provided. The shift register includes an input unit, an output unit, an electrostatic discharge unit and a reset unit. The input unit provides an input signal. The output unit is coupled to the input unit and a gate output terminal. The output unit outputs an output signal through the gate output terminal according to the input signal. The electrostatic discharge unit is coupled to the output unit. After the gate output terminal outputs the output signal, the electrostatic discharge unit pulls down a voltage of the gate output terminal according to a low gate voltage. The reset unit is coupled to the input unit and the output unit. After the electrostatic discharge unit pulls down the voltage of the gate output terminal, the reset unit resets a voltage of a bootstrap node.
