This invention provides a shift register, a driving circuit, a display panel, and a display device. In the shift register: a first input unit is used to write a signal to a first node; the control terminal of a first output unit is coupled to the first node, a first terminal of the first output unit receives a first voltage signal, and a second terminal of the first output unit is coupled to a signal output terminal; a second input unit is used to write a signal to a second node; the control terminal of the second output unit is coupled to the second node, a first terminal of the second output unit receives a first clock signal, and a second terminal of the second output unit is coupled to a signal output terminal; the output terminal of a sustaining unit is coupled to the second node, and the sustaining unit is used to maintain the potential of the second node at least during the period when the first output unit is off and the second output unit is on, ensuring that the potential of the second node is maintained during the period when an enable signal is output at the signal output terminal, thus ensuring the output state of the signal output terminal.
