Abstract:
An organic electroluminescence device includes a base material including a recessed portion on a surface side, a reflective layer disposed at least on a surface of the recessed portion, a filling layer having optical transparency, the filling layer being disposed in the recessed portion through the reflective layer, a first electrode having optical transparency, the first electrode being disposed at least on an upper-layer side of the filling layer, an organic layer including at least a light emitting layer, the organic layer being disposed on an upper-layer side of the first electrode, and a second electrode having optical transparency and light reflectivity, the second electrode being disposed on an upper-layer side of the organic layer. The filling layer includes at least one type of phosphor.
