Patent ID: 8405098

Claim:
An organic light emitting device, comprising: a first electrode on a substrate; a second electrode on the substrate; and a plurality of light emitting units between the first electrode and the second electrode, the plurality of light emitting units including a first light emitting unit that includes a first light emitting layer, and a second light emitting unit that includes a second light emitting layer, wherein, the first electrode reflects light from at least one of the plurality of light emitting units to generate an interference pattern with light emitted from the first light emitting layer, the interference pattern includes a plurality of interference positions, the plurality of interference positions being located at peak positions of the resulting interference between the reflected light and the light emitted from the first light emitting layer, and the plurality of light emitting units are positioned such that a first interference position is located within the first light emitting layer, and a second interference position is located within the second light emitting layer.
