ORGANIC LIGHT-EMITTING DEVICE |
摘要 |
An object of the present invention is to provide an organic light-emitting device, wherein light trapped in a substrate due to total reflection at the interface between air and a substrate is efficiently extracted to the air side. The organic light-emitting device includes: a transparent electrode; a counter electrode; a light-emitting layer interposed between the transparent electrode and the counter electrode; a front substrate which allows light from the light-emitting layer to exit to the outside from a surface of the front substrate on the opposite side to the light-emitting layer side; and a diffuse reflector which reflects light from the light-emitting layer, wherein the diffuse reflector is provided on a side surface of the front substrate and at a given position on a surface thereof.
