摘要：
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.
