Abstract
A method for producing an airtight container includes preparing an assembly having a first substrate and a frame member, the first substrate having an electron-emitting element formed on a first surface thereof, the frame member mounted on the first surface outside an area where the electron-emitting element is formed; forming a temporary assembly having the assembly and a second substrate by bringing the second substrate into contact with the frame member via a joining member such that an inner space is formed; melting the joining member by irradiating the joining member with a laser beam transmitted through the second substrate; and solidifying the melted joining member. The laser beam is applied such that an incident direction at an irradiation position on the joining member does not include components toward the interior of the frame member while the laser beam moves relative to the temporary assembly.
