Organic light-emitting device, method for manufacturing same, display device and illuminator

A method of fabricating an organic electroluminescent element comprising:

• a first electrode forming step for forming a first electrode above a substrate, a surface of the first electrode having a multidimensionally meandering surface shape surface, the surface being opposite to the other surface facing the substrate;
• an emissive layer forming step of forming an emissive layer by depositing an organic electroluminescent material approximately uniformly along the multidimensionally meandering surface of the first electrode, both surfaces of the emissive layer having a multidimensionally meandering surface shape, one surface of the emissive layer facing the first electrode, the other surface of the emissive layer being opposite to the one surface facing the first electrode;
• and
• a second electrode forming step of forming a second electrode above the emissive layer.
