Abstract

A vacuum-tight seal is produced between plate-shaped elements one of which is glass, of a gas discharge display device while maintaining such a pressure on the surface of the elements that they are brought in permanent contact with a spacing member which separates them. Furthermore, at least the glass face plate is preferably heated to such a high temperature that a possible elastic deformation of said element resulting from a pressure exerted on the surface thereof is converted into a plastic deformation.
