Claim Text:
1. A shift register comprising a plurality of stages of shift register circuits, a N th stage shift register circuit among the plurality of stages of shift register circuits comprising: a pre-charging circuit for pre-charging a pulling-up circuit; the pulling-up circuit for enabling an outputting terminal to output a high level after the pre-charging is completed; a resetting circuit for resetting the N a retaining circuit for retaining an output potential of the N a control terminal and an inputting terminal of the pre-charging circuit are connected with an outputting terminal of a previous stage shift register circuit, an outputting terminal thereof is connected with an inputting terminal of the resetting circuit; an inputting terminal of the pulling-up circuit is connected with a first control signal terminal; a control terminal of the resetting circuit is connected with an outputting terminal of a next stage shift register circuit, an outputting terminal thereof is grounded; the retaining circuit is connected with the outputting terminal of the pre-charging circuit, the inputting terminal of the resetting circuit, a control terminal of the pulling-up circuit and an outputting terminal of the pulling-up circuit, a first control terminal is connected with the first control signal terminal, and a second control terminal is connected with a second control signal terminal; and the retaining circuit is equipped with one transistor whose gate is connected with the first control signal terminal, source and drain are connected with each other.
