ORGANIC LIGHT EMITTING DEVICE, DISPLAY UNIT INCLUDING THE SAME, AND ILLUMINATING DEVICE INCLUDING THE SAME

摘要

An organic light emitting device includes a first electrode and second electrode on a substrate. Light emitting units are positioned between the first and second electrodes. A first light emitting unit includes a first light emitting layer, and a second light emitting unit includes a second light emitting layer. The first electrode reflects light from at least one of the light emitting units to generate an interference pattern with light emitted from the first light emitting layer. The interference pattern has a plurality of interference positions 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.
