Abstract
The present invention relates to an organic electroluminescence element in which a transparent first electrode, an organic light emitting layer, a second electrode are stacked on a translucent substrate in this order. The translucent substrate includes a moisture-proof layer facing the first electrode. An LR layer and an HR layer having a refractive index higher than a refractive index of the LR layer are situated between the moisture-proof layer and the first electrode in this order from the moisture-proof layer. An uneven structure is provided at an interface between the LR layer and the HR layer. A linear expansivity α of the moisture-proof layer, and a linear expansivity β of the LR layer, and a linear expansivity γ of the HR layer satisfy a relation of α≦β≦γ.
