    Abstract: The present application provides a gate driving circuit and a display device including a pull-up module, an isolation module, a pull-down maintaining module, and an inverting module. A coupling effect of an electric potential variation of a first node on an electric potential of a second node is blocked by providing the isolation module. Therefore, in a case that a clock signal fluctuates so that the electric potential of the first node fluctuates, that a change of the electric potential of the first node spreads to the electric potential of the second node is blocked, and the electric potential of the second node is stabilized. A failure of the gate driving circuit is improved.
