A method of manufacturing a light-emitting device, in which a light-emitting body is sealed between a substrate and a sealing body, includes forming a light-emitting layer, made of a light emitting material, on the surface of the substrate; forming the sealing body which partially covers the light-emitting layer; and removing portions of the light-emitting layer, which are not covered by the sealing body, using the sealing body as a mask, thereby forming the light-emitting body.
