A method of manufacturing an organic EL device that is capable of reducing the manufacturing cost by effectively using the material is provided. In the method of manufacturing the organic EL device including a white-light-emitting layer and a color filter, the white-light-emitting layer is formed by using a liquid droplet ejection method. Further, the color filters are also formed by using the liquid droplet ejection method. As a result, it is possible to reduce waste of the material and the manufacturing time.
