Organic light emitting device

An organic light emitting device comprises first and second electrodes; first and second stacks formed between the first electrode and the second electrode, the first and second stacks emitting their respective colors different from each other; and an intermediate layer formed between the first stack and the second stack, wherein the intermediate layer includes a first intermediate layer disposed to be adjacent to the first stack to provide electrons to the first stack, and a second intermediate layer disposed to be adjacent to the second stack to provide holes to the second stack, and the second intermediate layer includes a P doping charge generating layer formed on the first intermediate layer and a layer having hole transporting characteristic formed on the P doping charge generating layer.
