    Abstract: The present disclosure provides a shift register unit, a driving method thereof, a gate drive circuit, and a display device, and relate to the field of display technology. When a user's demand is changed, it is not necessary to regulate a pulse width of a signal inputted to a pixel circuit row by row, and a signal outputted from the shift register unit to the pixel circuit is stable. The shift register unit includes a first input circuit, a first output circuit, a second input circuit, a second output circuit, and a stabilizing circuit. The stabilizing circuit is configured to, when the first output circuit outputs a signal to a signal output terminal, stabilize a potential of a second node so that no signal is outputted from the second output circuit; or, when the second output circuit outputs a signal to the signal output terminal, stabilize a potential of a first node so that no signal is outputted from the first output circuit.
