Abstract
A plurality of light emitters emitting different colors of light in an organic light-emitting device, each light emitter including a first electrode, a first charge injection/transport layer, an organic light-emitting layer, an intermediate layer, a second charge injection/transport layer, and a second electrode, above a substrate. The intermediate layer includes a fluoride of an alkali metal or an alkaline earth metal. The second charge injection/transport layer includes an alkali metal or an alkaline earth metal. Of the first electrode and the second electrode, one electrode is light reflective and the other electrode is light transmissive. Of the first charge injection/transport layer and the second charge injection/transport layer, one charge injection/transport layer is disposed between the organic light-emitting layer and the one electrode, and thickness of the one charge injection/transport layer is different between a first light emitter and a second light emitter.
