摘要:
Provided is an organic electroluminescence element which is driven with a reduced drive voltage without deteriorating emission luminance and has a high power efficiency. The organic electroluminescence element having at least one light emitting layer is characterized in that two or more types of light emitting dopants having different emission colors are included in at least one light emitting layer, the concentration of all the light emitting dopants included in the light emitting layer is 5 Vol % or more, and the concentration of the light emitting dopant giving a main emission color among the light emitting dopants in the light emitting layer is 2 Vol % or less.
