Abstract
A gate driver according to an embodiment and a display device using the same are disclosed. The gate driver includes a plurality of signal transmitters, wherein an nth signal transmitter includes, a (1-1)th output circuit configured to output a carry signal to a first output node according to a voltage of a first control node and a voltage of a second control node, a (1-2)th output circuit configured to output a boosting signal to a second output node according to a voltage of the first control node and a voltage of the second control node, wherein the (1-2)th output circuit includes a pull-up transistor configured to apply a gate high voltage to the first output node, a pull-down transistor configured to apply a gate low voltage to the first output node, and a first capacitor connected between a gate of the pull-up transistor and the second output node.
