摘要： A shift register, a display apparatus, a gate driving circuit and a driving method, the shift register comprises a plurality of stages of shift register circuits (SR0-SRn), a N th stage shift register circuit among the plurality of stages of shift register circuits (SR0-SRn) comprises: a pre-charging circuit (1), a pulling-up circuit (2), a resetting circuit (3) and a retaining circuit, the retaining circuit is equipped with an eighth transistor (M8) whose gate is connected with a first control signal terminal (CK), source and drain are connected with each other. Not only a shift registering is realized, but also the operation period of the circuit is decreased, which can address the problem of shift in the voltage thresholds. Further, with the transistor whose source and drain are short-circuited, a control of the control signal on the pulling-down node is realized, so that a potential at the pulling-down node rises rapidly when the first control signal is in the high level and has a reduced descending range when the first control signal is in the low level, which can realize a better control of the circuit.
