Abstract
A gate driver includes stages coupled to each other and outputting gate signals. Each stage includes a node driver, a pull-up unit, a node controller, a first node stabilizer, and a pull-down unit. The node driver outputs a first voltage or a second voltage to a first node in response to a first or a second input signal. The pull-up unit pulls an output terminal to high in response to a voltage of the first node. The node controller outputs an on-voltage to a second node in response to a first clock signal from a third node or a second clock signal from a fourth node. The first node stabilizer stabilizes the first node to an off-voltage in response to a voltage of the second node. The pull-down unit pulls the output terminal to low in response to the voltage of the second node or the second input signal.
