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.
