Organic electroluminescence device, illumination device, and display device

An illumination device comprising:

• a base material having a top surface on which a recess is provided;
• a reflective layer provided along at least a surface of the recess;
• a filling layer filled in the recess via the reflective layer, the filling layer having light transmissivity;
• a first electrode provided at least on an upper layer side of the filling layer, the first electrode having light transmissivity;
• an organic layer provided on an upper layer side of the first electrode, the organic layer comprising at least a light emitting layer;
• and
• a second electrode provided on an upper layer side of the organic layer, the second electrode having light transmissivity,
• wherein the second electrode has a light reflectance of 70% or less.

A display device comprising:

• a base material having a top surface on which a recess is provided;
• a reflective layer provided along at least a surface of the recess;
• a filling layer filled in the recess via the reflective layer, the filling layer having light transmissivity;
• a first electrode provided at least on an upper layer side of the filling layer, the first electrode having light transmissivity;
• an organic layer provided on an upper layer side of the first electrode, the organic layer comprising at least a light emitting layer;
• and
• a second electrode provided on an upper layer side of the organic layer, the second electrode having light transmissivity,
• wherein the second electrode has a light reflectance of 70% or less.
