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-circuit, a second sub-circuit, and a leakage prevention circuit. The first sub-circuit includes a first input circuit and a first output circuit, the first input circuit is configured to control a level of a first node in response to a first input signal. The second sub-circuit includes a second input circuit and the second output circuit. The leakage prevention circuit is connected to the first node, and is configured to control a level of the leakage prevention node under control of the level of the first node, so that a circuit connected between the first node and the leakage prevention node is turned off, and a circuit connected between the second node and the leakage prevention node is turned off.
