Abstract
A gate driver includes a plurality of stages, wherein an n-th stage includes: a pull-up unit configured to output a high voltage of a clock signal as a high voltage of an n-th gate signal; a pull-down unit configured to decrease the high voltage of the n-th gate signal to a first low voltage; a discharging unit configured to discharge a voltage of the first node to a second low voltage lower than the first low voltage; a carry unit configured to output the high voltage of the clock signal as an n-th carry signal; an inverter unit configured to output a signal in synchronization with the clock signal; a first node storage unit configured to maintain the voltage of the first node at the second low voltage; and a second node storage unit configured to maintain the voltage of the second node at the first or second low voltage.
