Description of the Related Art In recent years, as TV receivers and OA equipment have become portable, a liquid crystal display has been increasingly used as a display device in order to make the equipment thinner. However, since the liquid crystal display does not emit light by itself, it is necessary to use some light source as a backlight to obtain the brightness of the display. A flat light source is used as the backlight of these liquid crystal displays. As the planar light source, a planar discharge light emitting element using the same light emitting principle as a fluorescent lamp may be used. The discharge light emitting element forms a discharge space with a transparent member such as glass,
An electrode is provided inside the discharge space, and a discharge gas is injected to manufacture. Therefore, in the process of manufacturing the discharge light emitting device, it is necessary to exhaust the air inside the discharge space and then inject the discharge gas. Therefore, the discharge light emitting element is provided with a glass tube called a tip tube for connecting the inside of the discharge space to the vacuum pump and the gas cylinder.
