Abstract
An organic electroluminescent element includes, in order, a first electrode, an organic light-emitting layer, a metal thin film including a metal or a metal alloy, an organic electron transport layer doped with a metal, and a second electrode. The metal in the metal thin film is identical to the metal doped in the organic electron transport layer. The metal alloy in the metal thin film includes a metal identical to the metal doped in the organic electron transport layer.
