Abstract: An organic EL device includes at least an anode, a first light-emitting layer, an intermediate layer, a second light-emitting layer, and a cathode in this order. The intermediate layer is adjacent to the first light-emitting layer and the second light-emitting layer. The first light-emitting layer and the second light-emitting layer can trap electrons. A material constituting the intermediate layer is a hydrocarbon that has a HOMO level equal to or lower than the HOMO level of a host of the first light-emitting layer and that has a high S1 level.
