Abstract:
An organic EL device according to one aspect of the present invention includes: a base material in which a recess is provided at an upper surface of the base material; a reflective layer that is provided at least along a surface of the recess; a filling layer that is filled into an inside of the recess via the reflective layer, the filling layer having light transmissivity; a first electrode that is provided at least on a layer above the filling layer, the first electrode having light transmissivity; an organic layer that is provided on a layer above the first electrode, the organic layer comprising at least a light-emitting layer; and a second electrode that is provided on a layer above the organic layer, the second electrode having light transmissivity and light reflectivity. A part of the reflective layer contacts a part of the first electrode.
