A shift register includes multiple cascade-connected stages. Each stage generates an output signal in response to a clock signal and a first control signal. Each stage includes a pull-up module, a pull-up driving module, a first pull-down module, a second pull-down module, and a third pull-down module. The pull-up module is used for providing the output signal based on the clock signal. The pull-up driving module turns on the pull-up module in response to a first control signal. The first pull-down module adjusts voltage level on the first node to a first supply voltage in response to a second control signal. The second pull-down module adjusts voltage level on the output end to a second supply voltage in response to the second control signal. The third pull-down module adjusts voltage level on the second node to a third supply voltage in response to a third control signal.
