An organic light-emitting device includes a first electrode layer, an emission layer, an electron transporting layer, an electron injection layer, and a second electrode layer sequentially formed from bottom to top. The emission layer includes a guest light-emitting material, a first phenyl phosphine oxide derivative and a hole transporting material. The electron transporting layer includes a second phenyl phosphine oxide derivative and a third phenyl phosphine oxide derivative different from the second phenyl phosphine oxide derivative. One of the second phenyl phosphine oxide derivative and the third phenyl phosphine oxide derivative is identical to the first phenyl phosphine oxide derivative. The electron injection layer includes an alkaline metal compound.
