摘要： An emission driver includes a plurality of stages. Each stage includes an input block that transfers an input signal to a control node, a control block that controls an inverted control node and applies a third low gate voltage to the inverted control node in response to a voltage of the control node, an emission signal output block that outputs a high gate voltage as an emission signal in response to the voltage of the control node and outputs a first low gate voltage as the emission signal in response to a voltage of the inverted control node, and a carry signal output block that outputs the high gate voltage as a carry signal in response to the voltage of the control node and outputs a second low gate voltage different from the first low gate voltage as the carry signal in response to the voltage of the inverted control node. The third low gate voltage is different from the first low gate voltage and the second low gate voltage.
