Abstract:
The organic EL device includes a base material, a recessed portion, a reflective layer provided along an inner face of the recessed portion, a filling layer having optical transparency, and filled and disposed at an inside of the recessed portion, with the reflective layer interposed between the recessed portion and the filling layer, a first electrode having optical transparency and provided at an upper-layer side of the filling layer, an organic layer including a light-emitting layer and provided at an upper-layer side of the first electrode, a second electrode having optical transparency and optical reflectivity and provided at an upper-layer side of the organic layer. At least a portion of an edge of the light-emitting region is positioned further inside than an edge of the recessed portion, and the reflective layer and the first electrode are in contact with each other at the periphery of the recessed portion.
