    Abstract: A gate driving circuit and a display device are disclosed. The gate driving circuit includes a shift register including a plurality of stages. Among the stages, an Nth stage includes a first transistor charging a Q node and a junction stress control circuit. A pull-up transistor using the Q node as a gate input controls an output signal of a stage output terminal. The junction stress control circuit includes a first, second, and third control transistors. The first control transistor, the second control transistor, the third control transistor, and the first transistor are connected to each other through a common node. The second control transistor adjusts junction stresses for the first control transistor and the first transistor by controlling a voltage of the common node. When the second control transistor is turned off, the third control transistor discharges the voltage of the common node.

    Abstract: A gate driver and a display device including the gate driver are provided which can prevent an abnormal output of a gate-high voltage from a stage by stably maintaining a discharge potential of a pull-up node. The gate driver includes a plurality of stages, and each stage includes a pull-up transistor that outputs a clock signal input to a first clock terminal to an output terminal depending on a voltage of a pull-up node; a pull-down transistor that outputs a first source voltage input to a first source voltage terminal to the output terminal depending on a voltage of a pull-down node; and a first noise removing unit that supplies a gate-off voltage to the pull-up node to remove noise of the pull-up node in response to the clock signal input to the first clock terminal.
