Organic electroluminescence device including auxiliary electrodes

摘要

According to one embodiment, in an organic electroluminescence device, a first substrate has a first refractive index n1. A second substrate is joined to an upper surface of the first substrate and has a second refractive index n2 higher than the first refractive index n1. Multiple wedge-shaped metal lines are buried in the second substrate in such a manner that one side of the wedge-shaped metal line is flush with an upper surface of the second substrate. A transparent electrode is formed on the upper surface of the second substrate and the multiple metal lines. An insulating layer is formed on a portion of the transparent electrode opposed to the multiple metal lines. An organic light emitting layer is formed on the transparent electrode on which the insulating layer is formed. A metal electrode is formed on the organic light emitting layer.
