An organic light emitting display including a scan driver for supplying scan signals to odd scan lines in an ith frame and for supplying scan signals to even scan lines in an (i+1)th frame, a data driver for supplying data signals corresponding to the scan signals, and an image display unit including a plurality of pixels coupled with the scan lines and the data lines. Pixels coupled with the odd scan lines do not emit light when the scan signals are supplied to the odd scan lines, and pixels coupled with the even scan lines do not emit light when the scan signals are supplied to the even scan lines.
