Gaseous discharge display devices require that certain physical parameters, such as the discharge gap between opposing cell walls, be maintained within close tolerances across the entire display area. In large area displays, interstitial spacers are bonded to the dielectric of one of the plates at predetermined intervals between conductor lines to provide and maintain a uniform discharge gap across the entire display surface. The number, configuration and position of the individual spacer elements will vary in accordance with the panel size as a function of the load bearing requirements. Such spacers may be metallic rods, such as nickel-iron alloy. Orientation of the spacer element with relation to the conductor lines is critical when the spacer is bonded to the dielectric surface of a plasma display substrate.
