Abstract
An organic light emitting device includes four sub-organic light emitting devices. The first device includes a first anode, a first common light emitting portion, and a first sub-light emitting portion. The second device includes a second anode, a second common light emitting portion, a first auxiliary layer, and a second sub-light emitting portion. The third device includes a third anode and a third common light emitting portion. The fourth device includes a fourth anode, a fourth common light emitting portion, and a light emitting layer emitting a first light. The first and second sub-light emitting portions have an integral structure and emit second light. The first, second, third, and fourth common light emitting portions have an integral structure and emit third light having a wavelength longer than a wavelength of at least one of the first or second lights.
