Organic electroluminescent element and illumination device

摘要

An organic electroluminescent element is provided with a light transmissive substrate, a light transmissive electrode, a counter electrode paired with the light transmissive electrode, a sealing substrate facing the light transmissive substrate, an organic light emitting layer, and a resin structure. The organic light-emitting layer is disposed between the light transmissive electrode and the counter electrode. The organic light emitting layer is sealed with the light transmissive substrate and the sealing substrate. The resin structure is disposed between the light transmissive electrode and the light transmissive substrate. The resin structure is composed of a plurality of resin layers including a high refractive index layer and a low refractive index layer with different refractive indices. The high refractive index layer contains a physisorption-based moisture-absorbing material.
