Abstract: An organic light emitting display device can include data lines; scan lines; subpixels; a data driver; and a scan driver, in which each of the subpixels includes: an organic light emitting diode; a driving transistor connected to the organic light emitting diode; a first transistor controlled by a first scan signal applied to a first gate node and connected between the driving transistor and a data line; a second transistor controlled by a second scan signal applied to a second gate node and connected between the driving transistor and a reference voltage line; a third transistor controlled by a data voltage applied to a third gate node and connected between the second gate node of the second transistor and the second scan line; and a storage capacitor connected between the first node and the second node of the driving transistor.
