An electroluminescent device may be constructed with a first electrode and a second electrode which are spaced apart from each other and face each other, an inorganic light emitting layer formed between the first and second electrodes, a dielectric layer formed on an inner surface of the second electrode, and a field emission layer which is formed on at least one of an upper or lower surface of the inorganic light emitting layer and which is made from nanorods having a large aspect ratio.
