Provided is a white organic electroluminescent (EL) device including multiple polymer light emitting layers. a white organic electroluminescent device includes a first polymer light-emitting layer and a second polymer light-emitting layer, both of which are formed between a first electrode and a second electrode. A highest occupied molecular orbital (HOMO) energy level of the first polymer light-emitting layer is in the range 5.0 eV through 5.4 eV, and a HOMO energy level of the second polymer light-emitting layer is higher than the HOMO energy level of the first polymer light-emitting layer. Colors emitted from both of the first and second polymer light-emitting layers are combined to produce a white color.
