    Abstract: An organic light emitting diode device includes a first electrode and a second electrode facing each other, a charge-generating layer interposed between the first electrode and the second electrode, a first light emitting unit that emits blue and is interposed between the first electrode and the charge-generating layer, and a second light emitting unit that emits white by combining the blue and is interposed between the second electrode and the charge-generating layer. The first light emitting unit includes a blue emission layer, a first charge transport layer disposed on one side of the blue emission layer and including an alkali metal complex compound and a first charge transport material, and a second charge transport layer disposed on one side of the first charge transport layer and including the alkali metal complex compound and a second charge transport material that has different charge mobility from the first charge transport material.
