Abstract: A shift register, a gate drive circuit, a display device, and a driving method for the same. The shift register comprises a first output sub-circuit, which provides, under control of an INPUT or a RESET, a signal of a CN or a CNB to a pull-up node, outputs, according to a voltage level of the pull-up node, a signal of a CK to an OUT, transmits, under control of a CKB, a signal of the CKB to a pull-down node, and pulls down, according to a voltage level of the pull-down node, a voltage level of the OUT; a second output sub-circuit, which outputs, during a scan output stage and under control of a GON, a signal of the OUT to a GOUT; and a transfer sub-circuit, which pulls down, during a scan transfer stage and under control of a GOFF, a voltage level of the GOUT.
