Disclosed is a method of manufacturing an organic electroluminescent
element comprising a substrate and provided thereon, a light emission
layer and at least one layer of a hole injecting layer, a hole
transporting layer, an electron injecting layer, and an electron
transporting layer, two layers of the light emission layer and the at
least one layer being adjacent to each other, the method comprising the
steps of (a) providing a first coating solution employing a first organic
solvent for one layer of the two layers and a second coating solution
employing a second solvent for the other layer of the two layers, the
first solvent being immiscible with the second solvent; (b)
simultaneously coating the first and second coating solutions on the
substrate so that the first coating solution is in contact with the
second coating solution; and (c) drying the coated.
