ABSTRACT: In gas discharge display panels of some dimension a fracture in the seal between the plate- shaped elements of the panel is obtained in many cases upon evacuating the panel. Said fracture is a result of the fact that the plate-shaped elements, for example the glass face plate of the panel, are not entirely flat so that said elements contact the intermediately located spacing members in an insufficient number of places. This problem is solved by producing the vacuum- tight seal between the plate-shaped elements while maintaining such a pressure on the surface of said element that they are brought in permanent contact with the spacing members. 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.
