Abstract: A gate driving circuit is provided. A gate driving circuit comprises a pull-up control unit including a control transistor, a pull-up unit, a carry unit which outputs a clock signal into a kth carry signal and a pull-down unit which pulls down a control node to an off voltage, wherein the control transistor includes one electrode and the other electrode connected to the control node, the one electrode and the other electrode being disposed on a gate electrode such that the one electrode and the other electrode being insulated from the gate electrode, wherein the gate electrode and the other electrode are disposed not to be overlapped with each other, and a distance between an upper surface of the gate electrode and a lower surface of the one electrode is longer than that of the upper surface of the gate electrode and a lower surface of the other electrode.
