The panel comprises a gas-filled envelope formed by a base plate and a face plate hermetically sealed together by a ring of fusible sealing material. The interior of the envelope includes a display area which consists of glow cathodes and one or more anodes. Adjacent to the display area and near one end of the panel is provided a source of mercury which comprises a glass capillary tube containing a droplet of mercury. The mercury capillary tube is supported by a generally C-shaped insulating layer which is formed when the ring of fusible sealing material is formed, and of the same material. This C-shaped layer, like the sealing ring, is in contact with, and lies between, the base plate and face plate. The glass capillary is embedded at one end and at about its midpoint in this seal material, with the opposite end being free and unsupported. The free end of the capillary can be shattered by a laser to release mercury vapor into the panel envelope.
