Abstract
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.
