Abstract: A shift register unit includes an input circuit, a first control circuit, a second control circuit, a third control circuit, a first output circuit, and a second output circuit. The first and second output circuits selectively transfer a first reference voltage from a first reference voltage terminal and a third reference voltage from a third reference voltage terminal to an output terminal of the shift register unit. This allows the shift register unit to output a desired output signal in an easy manner.
