Abstract: Provided herein is a light emission control driver according to an aspect of the present disclosure. The light emission control driver includes a plurality of stages, wherein each of the plurality of stages has a first circuit part configured to receive a first start signal and a second start signal and control a first node and a second node in response to a first clock signal, a third circuit part configured to output a second light emission control signal in response to a first control signal applied to the first node or a second control signal applied to the second node, and an output part configured to output a first light emission control signal in response to the first control signal or the second light emission control signal.
