A method of manufacturing an organic electroluminescent device has the steps of forming a first electrode on a substrate, preparing a solution containing a hole transport organic material, an electron transport organic material and a luminescent organic material, followed by spraying the solution onto the first electrode by using a pressurized gas so as to form an organic thin film layer, and forming a second electrode on the organic thin film layer.
