Abstract
In a gate driver including a plurality of stages sequentially outputting shifted signals, each of the stages includes a first controller for controlling a first node in response to a first scan signal and a second scan signal; a second controller for controlling second and third nodes in response to the first scan signal and a voltage at the first node; and an output unit for selectively outputting one of a plurality of clock signals and a first power supply voltage in response to voltages at the first, second and third nodes, wherein second and third power supply voltages different from each other are switched to be supplied to the second and third nodes.
