<p>The present invention provides an organic EL element configured to stably emit light while suppressing total reflection that occurs at an electrode. This organic EL element includes a pair of electrodes and one or more organic layers provided between the electrodes, and includes a light-emitting layer as the one or more organic layers. Surfaces of the pair of electrodes facing each other are flat. At least one organic layer of the one or more organic layers has a periodic structure that makes the traveling direction of light, traveling in the direction generally perpendicular to the thickness direction of the light-emitting layer, inclined to the thickness direction. The periodic structure has a periodic configuration that is arranged with a two-dimensional period in a plane that is perpendicular to the thickness direction of the light-emitting layer.</p> |
