Abstract
A shift register unit, a gate driving circuit, a display device, and a driving method are disclosed. The shift register unit includes a first sub-unit and a leakage prevention circuit; the first sub-unit includes a first input circuit and a first output circuit. The first input circuit controls a level of a first node in response to a first input signal, the first output circuit provides an output signal at an output terminal under control of the level of the first node, the leakage prevention circuit is connected to the first node and a first voltage terminal, and controls a level of a leakage prevention node under control of the level of the first node, whereby a conductive path is formed between the leakage prevention node and the first voltage terminal, and a circuit connected between the first node and the leakage prevention node is turned off.
