Abstract
(EN)
Disclosed is a light-emitting device comprising a light-emitting layer formed between a first electrode and a second electrode facing each other in parallel, an organic semiconductor layer formed between the light-emitting layer and the first electrode, and an auxiliary electrode arranged on a surface of the first electrode, which is opposite to the surface facing the second electrode, via an insulating layer. This light-emitting device is characterized by comprising a third electrode arranged within the organic semiconductor layer.
