Abstract
An organic electroluminescent element includes an optically transparent electrode, a counter electrode, an emission layer, an auxiliary reflective layer and a diffusion-preventing layer. The counter electrode is paired with the optically transparent electrode and formed of Ag or an alloy containing Ag and has light reflectivity. The emission layer is disposed between the optically transparent electrode and the counter electrode. The auxiliary reflective layer is disposed on an opposite side of the counter electrode from the emission layer. The diffusion-preventing layer is disposed between the counter electrode and the auxiliary reflective layer whose components are prevented from diffusing and moving therebetween.
