Abstract
Provided are a light emitting layer including molten salt and an organic electroluminescent device comprising the light emitting layer. When the organic electroluminescent device is operated, a field induction charge separation layer is formed in the light emitting layer including the molten salt and thus, carrier injection is improved, thereby providing a light emitting layer having improved light emitting efficiency. An organic electroluminescent device including the light emitting layer has low operating voltage and long lifespan.
