Abstract
The present invention provides a shift register, a gate driving circuit and a display device. The shift register comprises a precharge and reset module, a pull-up module, a pull-down module and a cut-off module, the cut-off module, the pull-up module and the pull-down module are connected at a first node, and the cut-off module is connected between the first node and the precharge and reset module. In the present invention, the cut-off module is provided to disconnect electric connection between the precharge and reset module and the pull-up module, such that the first node cannot discharge through the precharge and reset module, which effectively avoids internal discharge of the shift register, and further ensures normal output of the signal output from the output terminal of the shift register, and improves stability of the shift register.
