Abstract

The present invention provides an organic EL panel in which requirements apparently contrary to each other, namely reduction of damage to a solid layer during production of the organic EL panel and enhancement of rectification characteristics in the reverse bias direction can be satisfied. The organic EL panel of the present invention comprises a substrate, an anode, a solid layer including at least an organic light emitting layer, a cathode, and an upper film arranged in this order, and is characterized in that the cathode has an interface region with the upper film which is formed of an alloy containing magnesium at an atomic ratio of 50% or less such that the work function decreases from the interface region with the upper film toward that with the solid layer.
