Abstract
Provided is an organic electroluminescent lighting device which can be seen that the entire surface is uniformly illuminated from the side of a transparent electrode substrate even when an auxiliary electrode or an auxiliary wiring is provided with respect to the transparent electrode substrate. In an organic electroluminescent lighting device including a pair of electrode layers including a translucent electrode layer provided on a translucent substrate, at least one organic layer interposed between the pair of electrode layers and including a light-emitting layer, and an auxiliary electrode provided on the translucent electrode layer such that the auxiliary electrode comes in contact with a portion of the translucent electrode layer, the auxiliary electrode includes conductive metal particles having a particle diameter of 0.1 to 2 μm, and is covered with an interlayer insulating coating film for suppressing the conduction with the organic layer.
