Abstract: A shift register, a driving circuit and a display device are provided. The shift register comprises an output circuit, a node control circuit, and a first node charging circuit. The output circuit provides a signal at a first clock signal terminal or a signal at a first reference voltage terminal to a gate signal output terminal under a control of a signal at a first node or a control of a signal at a second node. The node control circuit controls levels of the signal at the first node and at the second node to be opposite. The first node charging circuit includes a first control terminal, and provides a signal at a first fixed voltage terminal to the first node under a control of a signal at the first control terminal during a charging period of the first node in a non-scanning period.
