Organic electroluminescent element, lighting apparatus, and method for manufacturing organic electroluminescent element

摘要

According to one embodiment, an organic electroluminescent element (110, 111, 112, 113) includes: a first electrode (10) having a first major surface (10a) and a second major surface (10b) on opposite side from the first major surface (10a) and having light transmissivity; a second electrode (20) opposed to part of the first major surface (10a); an organic luminescent layer (40) provided between the first electrode (10) and the second electrode (20); an optical layer (50) having a third major surface (50a) opposed to the second major surface (10b) and a fourth major surface (50b) on opposite side from the third major surface (50a). The fourth major surface (50b) includes a first region (50c) overlapping the second electrode (20), and a second region (50d) not overlapping the second electrode (20). The fourth major surface (50b) includes a first concave-convex (51a) provided in the first region (50c) and a second concave-convex (51b) provided in the second region (50d). A planarization layer (55) is provided on the second region (50d) and burying the second concave-convex (51b).
