Abstract
An organic light emitting display device pixel includes an organic light emitting diode (OLED). First, second and third transistors each have first, second and gate electrodes. A storage capacitor is connected between a power source and the first transistor gate electrode. A power source line is connected with a cathode electrode of the OLED for providing a voltage of either a high state or a low state. The second transistor is connected with a data line and a scan line and is turned on when a scan signal is supplied to the scan line. The first transistor is connected between the second transistor second electrode and an anode electrode of the OLED. The third transistor is connected between the gate and second electrodes of the first transistor and is turned on when the scan signal is supplied to the scan line.
