ABSTRACT:
Provided are a composition for an electron transport layer which can be wet coated at a low temperature, an electron transport layer manufactured by coating and drying the composition, and an organic electroluminescent device including the electron transport layer. The organic electroluminescent device including the electron transport layer manufactured by wet coating the composition for an electron transport layer has an improved electron injection into a light emitting layer, thereby having an excellent light emitting efficiency, low operating voltage, and improved lifespan.
