Organic electroluminescence device, organic electroluminescence unit, and electronic apparatus

An organic electroluminescence unit provided with a plurality of organic electroluminescence devices, one or more of the plurality of organic electroluminescence devices comprising, in order:

• a first electrode;
• a hole transport layer configured by a coated film;
• an organic light-emitting layer configured by a coated film;
• an electron transport layer;
• and
• a second electrode,
• wherein the organic light-emitting layer is made of an organic light-emitting material that has a molecular orientation degree specified by a parameter S′, the parameter S′ satisfying the following inequality:
• 0.66<S′<0.75, provided that
• S′={(2×ko)/(ke+2ko)}
• where ko denotes an extinction coefficient in a film-plane direction of the organic light-emitting layer, and ke denotes an extinction coefficient in a film-thickness direction of the organic light-emitting layer.
