ABSTRACT:
An organic electroluminescent device including at least an anode, a first emitting layer, a hole barrier layer, a second emitting layer and a cathode in this order. The first emitting layer and the second emitting layer both include a hole transporting material. The organic EL device is small in chromaticity change and has high efficiency.
