Abstract
An emission driver includes stages. At least one of the stages has a carry control node outputting a carry signal and an emission control node outputting an emission signal that are separated. Further, a second low gate voltage may be used that may be lower that a first low gate voltage. Further, transistors between each of the carry and emission control nodes and a second low voltage line transferring the second low gate voltage may have a series two transistor structure. Further, a transistor outputting the second low gate voltage as the carry signal may be repeatedly turned on and off in response to an inverted low clock signal. Accordingly, operation reliability of the emission driver of the display device may be improved.
