Patent ID: 10535717

Abstract:
A plurality of light emitters emitting different colors of light in a light-emitting device is provided on a surface of a substrate along two dimensions. Each light emitter includes a first electrode, a first charge injection/transport layer, a light-emitting layer, an intermediate layer, a second charge injection/transport layer, and a second electrode. The intermediate layer includes a fluoride of an alkali metal or an alkaline earth metal. Among the first electrode and the second electrode, one electrode is light reflective and another electrode is light transmissive. Among the first charge injection/transport layer and the second charge injection/transport layer, one charge injection/transport layer is disposed between the light-emitting layer and the light reflective electrode, and thickness of the one charge injection/transport layer included in the first light emitter is different from thickness of the one charge injection/transport layer included in the second light emitter.
