Abstract:
This organic EL element (10) is provided with a first electrode (12), an organic layer (13) containing a light-emitting layer comprising an organic EL material, and a second electrode (14) in this order on a substrate (11), and is configured to pull light from the first electrode side to the outside. The second electrode (14) comprises a plurality of emission origin points that are cyclically arranged on the surface (14A) of the organic layer side thereof. A dielectric layer (17) that has a lower refractive index than the organic layer (13) and that comprises a plurality of openings is provided between the first electrode (12) and the second electrode (14). The organic layer (13) comprises an opening inner surface covering section (13a) that covers the inner surface of the openings (17A). A cycle (λ1) in which the openings (17A) are arranged and a cycle (λ2) in which the emission origin points (14a) are arranged correspond in at least one in-plane direction of the element.
