Abstract

An organic electroluminescence device according to one aspect of the disclosure includes a base material including a recessed portion on an upper face, and a light emitting element including a reflective layer, a filling layer having optical transparency, a first electrode having optical transparency, an organic layer including at least a light emitting layer, and a second electrode having optical transparency. The reflective layer is disposed at least on a surface of the recessed portion. The filling layer is disposed at an inside of the recessed portion with the reflective layer interposed between the recessed portion and the filling layer. The first electrode is disposed at least on an upper-layer side of the filling layer. The organic layer is disposed on an upper layer of the first electrode. The second electrode is disposed on an upper-layer side of the organic layer. The organic electroluminescence device includes a display region that is divided into a plurality of unit regions. The plurality of unit regions each having the light emitting element has a light emitting area and a transmissive area that are partitioned.
