An organic electroluminescent device including in sequence an anode, a
first emitting layer (5), a carrier barrier layer (6), a second emitting
layer (7) and a cathode stacked; wherein the ionization potential of the
carrier barrier layer (6) is more than the ionization potential of the
first emitting layer (5) by 0.1 eV or more and the affinity level of the
carrier barrier layer (6) is less than the affinity levels of the first
emitting layer (5) and the second emitting layer (7) by 0.1 eV or more.
