Abstract: A substantially rectangle shaped frame for holding a flat-shaped electrode unit 7 is fixed to a rear panel 2 at four intermediate parts of the frame and is elastically held by a resilient retaining member 55a- - - 55d and 56a- - - -56d at four corners of the frame. Thereby, an engagement between the rear panel 2 and the flat-shaped electrode unit 7 via the frame is stably retained regardless of difference in degrees of deformations thereamong.

Abstract: A substantially rectangle shaped frame for rigidly affixing a flat-shaped electrode unit to a rear panel at intermediate parts of the frame and elastically attaching the frame to the rear panel by a resilient retaining member at four corners of the frame, thereby, stabilizing an engagement between the rear panel and the flat-shaped electrode unit via the frame regardless of difference in degrees of deformations thereamong.

Abstract: An image display device displays an image based on visible fluorescent radiation caused by electron beams emitted from a plurality of parallel spaced filamentary cathodes that extend over a substrate. A pair of support bars fixed to opposite sides of the substrate has a pair of spaced arrays of through holes defined therein, and supports a pair of spaced arrays of electrically conductive pins extending through through holes, with a plurality of electrically insulating bodies disposed around the electrically conductive pins and fitted in the through holes, respectively. Each of the filamentary cathodes has opposite ends secured to the support member and held against outer circumferential surfaces of one pair of electrically conductive pins of the spaced arrays.

Abstract: A flat panel display device which comprises a face glass plate, a metal container assembled to the face glass plate through a frit glass for providing an envelope for accommodating electron beam generating means and electron beam control means, the metal container including an outer container made of a thin metal plate and an inner container separately assembled to the inside of the outer container for acting as a pressure resistive container for supporting air pressure. Only the outer container is joined to the face glass plate.
