PURPOSE: An emission driver and an organic light emitting display device thereof are provided to reduce an afterimage by controlling pulse width and the number of pulse of a light control signal. CONSTITUTION: In an emission driver and an organic light emitting display device thereof, A plurality of stages receives first and second power sources to drive a light control signal. A first signal processing unit(411a) generates a first output signal in response to the first and second power sources A second signal processing unit(412a) outputs the lighting control signal inverting the first output signal. A third signal processing unit(413a) transfers the first or second powers to the first signal processing unit. A fourth signal processing unit(414a) generates a negative light control signal in response to the first output signal.
