Document Type and Number:
WIPO Patent Application WO/2014/083693
Kind Code:
A1
Abstract:
A light emitting device (100) comprises: a light transmissive substrate (110); a first light transmissive electrode (130) disposed opposite the light emission surface (light extraction surface (110a)) of the light transmissive substrate (110); an organic function layer (140) including at least a light emitting layer; a light reflection layer (160); and a light transmissive interposing layer (120). The interposing layer (120) is disposed between the organic function layer (140) and the light reflection layer (160). The interposing layer (120) is constituted by a first layer (121) and a second layer (122) that have mutually different refractive indexes, and are laminated alternately in three or more layers, the interposing layer (120) having two or more interfaces therein.
