ABSTRACT:
A flat display includes a front panel having a fluorescent screen on its rear side, a rear panel defining a flat space with the front panel, linear filament cathodes arranged close to the rear panel, and an address electrode plate having a multiplicity of apertures and disposed close to the front panel. The rear panel is formed on its inner surface with spacer ridges each extending on each side of each filament cathode therealong and having a height to reach the address electrode plate. The spacer ridges give the flat display improved strength against pressure.
