Abstract: A shift register circuit includes plural shift register stages for providing plural gate signals. Each shift register stage includes a pull-up unit, a pull-up control unit, an input unit, a first pull-down unit, a second pull-down unit, and a pull-down control unit. The pull-up control unit generates a first control signal according to a driving control voltage and a first clock. The pull-up unit pulls up a corresponding gate signal according to the first control signal. The input unit is utilized for inputting the gate signal of a preceding shift register stage to become the driving control voltage according to a second clock having a phase opposite to the first clock. The pull-down control unit generates a second control signal according to the driving control voltage. The first and second pull-down units pull down the corresponding gate signal and the first control signal respectively according to the second control signal.
