Organic Electroluminescent Device

摘要

Provided is an organic electroluminescent device including, in an order mentioned: a reflective electrode; an organic electroluminescent layer; a light extraction layer; and a transparent substrate, wherein a ratio (w/d) is 9 or more where "d" denotes a total average thickness from the organic electroluminescent layer to the transparent substrate and "w" denotes a minimum width of a non-light-emitting region present outside of an outer periphery of an effective light-emitting region in the organic electroluminescent layer.
