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.

Abstract: The disclosure relates to an organic electroluminescence element including: a first substrate on a light extraction side thereof; a second substrate opposite the first substrate; and an organic light-emitting laminate between the first substrate and the second substrate. The first substrate includes a doped region in a surface close to the organic light-emitting laminate, the doped region being doped with a dopant for causing change in a refractive index of the first substrate to enhance a light-outcoupling efficiency.
