ORGANIC ELECTROLUMINESCENT ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide an organic electroluminescent element having a high emission efficiency and a long life. SOLUTION: The organic electroluminescent element has an organic thin-film layer held between an anode and a cathode. The organic thin-film layer includes one layer or a plurality of layers including at least a light-emitting layer. The organic thin-film layer contains at least one kind selected from asymmetrical pyrene derivatives having a specific structure as a single component or a component of a mixture.
