Claim:
1. A method of manufacturing a sealed body, comprising steps of: forming a frit glass layer along a continuous closed curve line over a first substrate; forming a reflective layer over a second substrate, the reflective layer comprising a first region, a second region and a third region; wherein the first region is provided in a corner region of the reflective layer, wherein the second region and the third region are provided in regions other than the corner region of the reflective layer, forming a first terminal and a second terminal over the reflective layer, the first terminal and the second terminal intersecting with the frit glass layer and the reflective layer; disposing the first substrate and the second substrate so that entirety of the reflective layer is provided under the frit glass layer; and scanning and irradiating the frit glass layer with laser light to weld the frit glass layer to the second substrate, wherein each of the first region and the second region has lower reflectivity than the third region, wherein the first terminal and the second terminal extend in parallel with each other when seen from a top of the sealed body, wherein the frit glass layer and the reflective layer are provided between the first substrate and the second substrate, wherein the scanning is started from the second region and ended at the second region, and wherein an amount of heat from laser light applied to the second region is substantially equal to an amount of heat applied to each of the first region and the third region without adjusting irradiation intensity.
