Abstract: The organic electroluminescence element includes: a moisture-proof substrate; a light emitting stack including a first electrode, a light emitting layer, and a second electrode; and an enclosing member bonded to the substrate to enclose the stack. The element further includes a light-outcoupling structure provided on a side of the substrate facing the first electrode and having an uneven structure made of material having a refractive index almost equal to or lower than a refractive index of the substrate. The uneven structure includes a plane divided into a matrix of sections, and multiple protruded parts having almost same heights individually allocated to desired sections of the matrix. With regard to an arbitrary region of the plane, a ratio of a total area of one or some of the multiple protruded parts in the arbitrary region to an area of the arbitrary region is almost constant.

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.
