Abstract: An organic light emitting display (OLED) device includes an organic light emitting diode having an anode and a cathode. The organic light emitting diode is configured to receive a reference voltage. A control transistor includes a first control electrode and a first semiconductor active layer. The control transistor is configured to receive a control signal. A driving transistor includes a second control electrode that is electrically connected to the control transistor, an input electrode that is configured to receive a power voltage, an output electrode that is electrically connected to the anode of the organic light emitting diode, and a second semiconductor active layer that includes a different material from that of the first semiconductor active layer. A shielding electrode is disposed on the second semiconductor active layer, overlapping the driving transistor, and configured to receive the power voltage.
