Abstract
A shift register including a voltage set unit, a driver unit, a control unit, a first transistor, a second transistor, a third transistor and a fourth transistor is provided. The voltage set unit provides a terminal voltage. The driver unit provides a main gate signal according to the terminal voltage and a clock signal. The control unit provides a control signal. The first transistor receives the terminal voltage, a level reference voltage and the control signal. The second transistor is coupled to the first transistor and receives a low voltage and the control signal. The third transistor receives the terminal voltage, a level reference voltage and a gate reference signal. The fourth transistor is coupled to the third transistor and receives the low voltage and the gate reference signal.
