摘要： An object is to provide a manufacturing method of a light emitting device, by which manufacturing costs in manufacturing a flat panel display can be reduced. A first substrate provided with a reflective layer having an opening over a first surface, and provided with a light absorption layer and an evaporation material over a second surface facing the first surface is used. Then, in a state where the second surface of the first substrate is disposed close to a first surface of a second substrate, light irradiation is performed from the first surface side of the first substrate. The irradiation light is absorbed by a portion of the light absorption layer overlapping with the opening in the reflective layer, thereby heating the evaporation material. The heated evaporation material is attached to the first surface of the second substrate.
