Abstract:
1. An organic luminescent device comprising: a substrate having first and second principal surfaces which are opposed to each other; an organic luminescent layer arranged on the first principal surface of the substrate and held between a pair of electrodes, at least one of the pair of electrodes being a transparent electrode; a reflection electrode adjacent to a luminescent area of the organic luminescent layer, the reflection electrode being arranged on any one of a front surface and a back surface of the transparent electrode, wherein the transparent electrode is arranged on the first principal surface of the substrate, the reflection electrode is arranged between the transparent electrode and the first principal surface, the second principal surface of the substrate is formed into a rough surface at least on its part opposed to the reflection electrode, and the first principal surface of the substrate and a surface of the reflection electrode that is in contact with the first principal surface are each formed into a rough surface.
