Abstract
According to one embodiment, a method of manufacturing an organic EL device includes 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 has a first sublimation point. The second organic material has a second sublimation point higher than the first sublimation point. The formation of the organic layer includes 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, 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. The evaporation temperature is, for example, a temperature higher than the second sublimation temperature by 50° C. or more.
