A shift register circuit includes plural shift register stages for providing plural gate signals to plural gate lines. Each shift register stage includes a pull-up unit, an input unit for receiving an input signal, an energy-store unit for providing a driving control voltage in response to the input signal, a discharging unit, a couple unit and a pull-down unit. The pull-up unit pulls up a first gate signal in response to the driving control voltage. The discharging unit performs a discharging operation for pulling down the driving control voltage. The couple unit is utilized for coupling the energy-store unit with a succeeding shift register circuit stage so that the falling edge of a second gate signal generated by the succeeding shift register stage is capable of shifting down the driving control voltage. The pull-down unit pulls down the first gate signal in response to the second gate signal.
