<P>PROBLEM TO BE SOLVED: To provide an organic electric field light-emitting element that achieves low voltage operation without deteriorating external quantum efficiency. Ž<P>SOLUTION: In the organic electric field light-emitting element having an organic layer that includes first and second electron transport layers between an anode and cathode and an interlayer between the first and second electron transport layers, the interlayer includes non-metal complex. The thickness of the interlayer is preferably 0.5-20 nm. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
