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.

Abstract: A gate driving circuit from which stable gate signals may be output by minimizing a leakage current of turned-off transistors in case that pull-down transistors output a gate signal and a carry signal of a low-level voltage. Some transistors in the gate driving circuit include two transistors in series to reduce leakage current in an off state, and capacitors are further included to reduce leakage current. Therefore voltages at nodes can be better controlled, and so that the output gate and carry voltages can be stably controlled.
