Abstract:
An organic electroluminescent element containing organic layers sandwiched between an anode and a cathode, wherein the organic layers incorporate an emission layer A containing a host compound A and at least two types of emission dopants, and an emission layer B containing a host compound B and at least one type of emission dopant, provided that at least one of the emission dopants contained in the emission layer A is a phosphorescence-emitting material.
