Abstract: An organic light emitting display device includes a plurality of pixels at areas defined by intersections of scan lines, emission control lines, and data lines. A data driver supplies data signals to the data lines. A scan driver supplies scan signals to the scan lines and progressively supplies a reference power source voltage and an emission control signal to the emission control lines. The reference power source voltage is set to a voltage greater than a voltage of the scan signal and less than a voltage of the emission control signal.
