ABSTRACT:
An organic electroluminescent device comprising an organic layer is provided. The organic layer is an electron transport layer comprising an electron transport material and a blue emission material. This electron transport layer causes an increase in the blue emission efficiency and lifespan of the organic electroluminescent device while improving efficiency in red and green ranges, a driving voltage, a color coordinate, and the lifespan of the organic electroluminescent device are not changed.
