A sealed body which is sealed with low-melting-point glass and has high airtightness is provided. In the sealed body, at least a wiring layer is provided between two facing substrates, the two substrates are bonded together with the use of a sealing layer containing glass frits as a material, and a metal layer is selectively provided in a region where the wiring layer and the sealing layer overlap. In a laser light irradiation step, the metal layer functions as a laser light reflecting film and suppresses application of excess energy to a sealing member in a region overlapping with the wiring layer.
