Patent ID: 8114703

Claim:
A method of manufacturing an organic EL device, comprising: providing a structure including a substrate and an electrode positioned above the substrate; and forming an organic layer including a mixture of first and second organic materials above the electrode, the first organic material having a first sublimation point SP 1 , the second organic material having a second sublimation point SP 2 higher than the first sublimation point SP 1 , and the formation of the organic layer comprising heating an evaporation material including a mixture of the first and second organic materials to an evaporation temperature so as to sublimate the first and second organic materials, the evaporation temperature being one of first to third temperatures, the first temperature being a temperature higher than the second sublimation temperature SP 2 by 50° C. or more, the second temperature being equal to or higher than a sum of the first sublimation temperature SP 1 and a product of 150/370 and the first sublimation temperature SP 1 , and the third temperature being equal to or higher than a sum of the second sublimation temperature SP 2 and a product of 50/370 and the second sublimation temperature SP 2 , and delivering the sublimed first and second organic materials toward the electrode to deposit a mixture including the first and second organic materials above the electrode.
