Abstract: An organic light emitting display device includes a substrate, a light emitting diode disposed on the substrate, and a balance electrode insulated from the light emitting diode and from each of the first and second electrodes. The light emitting diode includes a first electrode, a second electrode facing the first electrode, and an organic light emitting layer disposed between the first electrode and the second electrode. The balance electrode maintains a hole-electron charge balance within the organic light emitting layer by varying the amount of electrons and holes that are injected into the organic light emitting layer from the first and second electrodes by varying an electric potential applied to the balance electrode.
