Abstract
An emission driver includes a plurality of stages. A stage of the plurality of stages receives a start signal, a first clock signal, a second clock signal, a protection signal, a first gate power voltage and a second gate power voltage and outputs an emission signal. The stage of the plurality of stages includes a pull-up switching element connected between a first gate power voltage terminal which receives the first gate power voltage and an emission signal output terminal which outputs the emission signal, a pull-down switching element connected between a second gate power voltage terminal which receives the second gate power voltage and the emission signal output terminal and a protection switching element which applies the first gate power voltage to a control electrode of the pull-down switching element in response to the protection signal.
