A shift register including a plurality of multi-stage shift register circuits is provided. The mth stage shift register circuit includes a node, a shift register unit and a control circuit. A first control signal, enabled in an mth period, is defined on the node. The shift register unit is controlled by an (m−1)th stage output signal provided by an (m−1)th stage shift register circuit and a clock signal for providing the enabled mth stage output signal in the mth period, and controlled by an (m+1)th stage second control signal provided by an (m+1)th stage shift register circuit for providing a disenabled mth stage output signal in the (m+1)th period. The control circuit, controlled by the clock signal, provides and outputs an mth stage second control signal to the (m−1)th stage shift register circuit according to the mth stage first control signal, wherein m is a natural number greater than 1.
