An object is to provide a manufacturing method of a light-emitting device including an organic compound layer, in which a desired organic compound layer is easily formed using a plurality of evaporation materials. A first organic compound layer containing a plurality of evaporation materials is formed over a first substrate. The first organic compound layer is formed using a mixture formed by mixture of the plurality of evaporation materials in advance. A second substrate is placed at a position facing the first substrate so as to face the first organic compound layer provided for the first substrate. The first organic compound layer as an evaporation source is heated to be vaporized and a desired second organic compound layer is formed over the second substrate placed so as to face the first substrate. Accordingly, a light-emitting device is manufactured.
