Gate driver and display device including the same

A gate driver may include: a controller to charge and discharge a first control node that pulls up an output voltage and a second control node that pulls down the output voltage; a first output unit having a first pull-up transistor to apply a gate high voltage to an output node in response to a charging voltage of the first control node, and a first pull-down transistor to apply a gate low voltage to the output node in response to a charging voltage of the second control node; and a switch unit to change a current path between a first output node and a first power line to which a high potential voltage is applied or a second power line to which a first clock signal is applied according to a carry signal transmitted from a previous signal transmission unit and a voltage level of the second control node.
