Abstract
An organic electroluminescence device includes a base material including a recessed portion on one face side, and a light emitting element. The light emitting layer including a reflective layer disposed at least on a surface of the recessed portion, a filling layer that has optical transparency and is filled and disposed in the recessed portion with the reflective layer interposed between the recessed portion and the filling layer, a first electrode that has optical transparency and is disposed at least on an upper-layer side of the filling layer, an organic layer that includes at least a light emitting layer and is disposed on an upper layer of the first electrode, and a second electrode that has optical transparency and is disposed on an upper-layer side of the organic layer. The organic electroluminescence device includes a display region divided into a plurality of unit regions separated from each other. The unit regions each has a light emitting area and a non emissive area that are partitioned. The light emitting area includes the light emitting element, and the non emissive area includes a light absorption layer.
