ORGANIC ELECTROLUMINESCENT ELEMENT

摘要

Disclosed is an organic electroluminescent element which is characterized by sequentially comprising, between a positive electrode (20) and a negative electrode (60) facing each other, a light emitting layer (40) and an electron transport band (50) in this order from the positive electrode (20) side. The organic electroluminescent element is also characterized in that: a barrier layer (51) is provided in the electron transport band (50) so as to be adjacent to the light emitting layer (40); the barrier layer (51) contains a fused hydrocarbon compound and a compound(s) selected from among electron-donating dopants and/or organic metal complexes containing an alkali metal; and the triplet energy of the fused hydrocarbon compound is 2.0 eV or more.
