Plasma display panel and a process for producing the same.

摘要

An enclosure defined between two panel members is filled with a discharge gas. One of the panel members carries a sealing material (6) surrounding the enclosure and has an evacuating and gas-filling port (2), while the other panel member carries a port blocking member (27) formed in an appropriate positional relation to the port. The whole is heated, so that the sealing material may soften and join the panel members to each other along the edges thereof and form a gas-tight seal therebetween, while the blocking member also softens to close the port. The softened blocking member stays within the enclosure and the port. Nothing projects from either of the panel members at any angle thereto. A strong plasma display panel having only a minimum thickness as required can, therefore, be realized. If the joining of the panel members and the closing of the port are simultaneously carried out, the panel can be made quickly and at a low cost. The closing of the port can alternatively be done after the joining of the panel members. <IMAGE>
