Abstract: An organic light emitting device includes an anode, a cathode, and an organic layer between the anode and the cathode, wherein the organic layer includes an emission layer, an electron transport layer, and an assistance layer interposed therebetween, and the assistance layer has a higher HOMO level than the electron transport layer by more than 0.3 eV. The accumulation of holes in the electron transport layer is decreased or prevented by the gap of the HOMO level between the assistance layer and the electron transport layer such that the lifetime of the organic light emitting device may be increased.
