A shift-register circuit. The PMOS transistor includes a first gate for receiving an inverted output signal output from a previous stage shift-register unit, a first source for receiving an output signal from the previous stage shift-register unit, and a first drain. The first NMOS transistor includes a second gate coupled to the first drain, a second drain coupled to the clock signal and a second source. The capacitor is coupled between the second gate and the second source. The second NMOS transistor includes a third gate coupled to the first source, a third drain coupled to the second source and a third source coupled to the ground level. The third NMOS transistor includes a fourth gate coupled to an output of a next stage shift-register unit, a fourth drain coupled to a connection point of the second gate and the capacitor and a fourth source coupled to the ground level. The first inverter is coupled to a connection point of the first NMOS transistor and the second NMOS transistor to output an inverted output signal. The second inverter is coupled to the first inverter to output an output signal.
