Abstract
Provided is a method of manufacturing an organic light emitting device including the step of forming an electron injection layer. The step of forming the electron injection layer includes the steps of: vaporizing in a container a dopant material as a raw material of a dopant; causing the vaporized dopant material to pass a heated medium between the container and the substrate; and forming the organic compound into the electron injection layer. According to the method the organic light emitting device which has high electron injection efficiency and can be driven at a low voltage can be obtained.
