Abstract:
1. A method for manufacturing a light-emitting device, comprising the steps of: disposing a first substrate and a second substrate so that one surface of the first substrate faces a deposition surface of the second substrate, wherein the first substrate includes a reflective layer including an opening, a light absorption layer covering the opening in the reflective layer over the reflective layer, a protective layer including a trench portion in a position overlapped with the opening in the reflective layer over the light absorption layer, and a material layer including a light-emitting material over the protective layer; and forming an EL layer including the light-emitting material in a region overlapped with the opening in the reflective layer on the deposition surface of the second substrate by performing light irradiation from the other surface side of the first substrate, wherein the protective layer has a lower heat conductivity than the reflective layer and the light absorption layer, wherein the protective layer has a first region which is overlapped with the reflective layer and a second region which is not overlapped with the reflective layer, and wherein the first region is thicker than the second region.
