A shift register apparatus including a first shift register cell is disclosed. The first shift register cell includes a first logic unit, a first control unit and a first output unit. The first logic unit generates a first control signal and a second control signal according to a start signal and a first setting signal. During a first period, the first control unit employs the first and second control signals to make a first clock signal update the first setting signal and the first output unit employs the first and second control signals to make a second clock signal update the first shifted signal. During a second period, the first output unit controls the first shifted signal according to the first and second control signals such that the first shifted signal does not follow the second clock signal.
