Patent ID: 8053024

Claim:
A method of manufacturing an organic electroluminescent device comprising a cathode, an anode and a plurality of organic compound layers placed between the cathode and the anode, the method comprising: forming at least two of the organic compound layers on the cathode or on the anode by a coating method, wherein at least one of the organic compound layers other than the organic compound layer adjacent to the anode is formed by coating a dispersion and then subjecting the coated dispersion to a smoothing treatment, and wherein the coated dispersion contains a component of the organic electroluminescent device dispersed in a solid state; and organic compounds contained in the plurality of organic compound layers each has a dissolvable range of solubility parameter of from 8.3 to 10.6 (cal/cm 3 ) 1/2 and a solvent in the dispersion has a solubility parameter of from 7.0 to 8.2 or 10.7 (cal/cm 3 ) 1/2 to 23.0 (cal/cm 3 ) 1/2 .
