Zusammenfassung:An organic light emitting display, a method for driving the same, and a method for manufacturing the same are discussed. The organic light emitting display according to an embodiment includes a panel including subpixels each having a compensation circuit including a reference voltage supply transistor, which receives a reference voltage and initializes a node of a gate electrode or a drain electrode of a driving transistor using the reference voltage, a scan driver supplying a scan signal to scan lines of the panel, a data driver supplying a data signal to data lines of the panel, a timing controller that controls the scan driver and the data driver, and a reference voltage compensation unit supplying the reference voltage including a reverse voltage opposite a ripple generated in the reference voltage to the subpixels and cancel the ripple.
