An organic light emitting display, in which one frame is divided into an initializing period, a compensation period, a scan period, and an emission period, includes pixels at intersections of scan lines and data lines, the pixels coupled to a first power source and a second power source, a scan driver simultaneously supplying scan signals to the scan lines for a partial period of the initializing period, the scan driver simultaneously supplying scan signals to the scan lines for the compensation period, and the scan driver sequentially supplying scan signals to the scan lines for the scan period, a data driver supplying data signals to the data lines in synchronization with the scan signals supplied for the scan period, and a first power source driver supplying the first power source, the first power source having different voltage levels for the initializing period, the scan period, and the emission period.
