An organic light emitting display has increased flexibility in controlling the voltage range of data signals. The organic light emitting display includes a scan driver for driving scan lines and emission control lines, a data driver for supplying data signals to data lines, pixels positioned at crossing regions of the scan lines and the data lines, first power source lines coupled to a first power source and the pixels, horizontal power source lines coupled to the pixels, a second power source line coupled to a second power source different from the first power source, and first switching elements respectively coupled between the horizontal power source lines and the second power source line. Each of the pixels stores a voltage corresponding to the second power source and the data signal and controls an amount of current that flows from the first power source to correspond to the stored voltage.
