Organic electroluminescence device including a micro-cavity light extraction structure

An organic electroluminescence device comprising:

• a base material in which a recess is provided at a first 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, wherein
• a portion of the reflective layer contacts a portion of the first electrode,
• the first electrode includes a step that extends along an edge portion of the recess, and
• the first electrode contacts the reflective layer at the edge portion.
