An organic light emitting display includes a pixel circuit having first, second, and third organic light emitting diodes (OLEDs), for emitting red, green, and blue light, respectively, a driving circuit commonly connected to the OLEDs, and a switching circuits connected to the OLED and the driving circuit to sequentially control the driving thereof. By controlling a plurality of OLEDs, the number of pixel circuits in an organic light emitting display is reduced, thereby reducing the number of scan lines, data lines, and emission control lines, which in turn improves the aperture ratio of the light emitting display. Further, the emission order of the OLEDs is controlled so that it is possible to prevent the generation of color breakup.
