Abstract: A cathode ray tube includes a rectangular panel on which a phosphor screen is formed, and a neck in which an electron gun assembly for emitting three electron beams is disposed. The cathode ray tube also has a funnel including a neck seal part at which the neck and the funnel are connected, a cone part formed contiguous to the neck seal part, and has a non-circular section having a maximum diameter along a direction other than a long axis and a short axis of the panel; and a body formed contiguous to the cone part and the panel. In the cathode ray tube, inflection points are formed between the cone part and the body, and the inflection point at a diagonal direction of the panel is formed nearer to the panel than the inflection points at the long axis and the short axis.

Abstract: An envelope of a cathode ray tube includes a substantially rectangular flat face plate, and a substantially rectangular flat rear plate opposed to the face plate with a side wall being interposed therebetween, a plurality of funnels extending from the rear plate. A plurality of necks extend from the respective funnels, and a plurality of electron guns are respectively arranged in the necks. A plurality of plate support portions are arranged between the rear plate and the face plate, so as to support the rear plate and the face plate against an atmospheric pressure. Each plate support portion includes a support body made of glass which is integrally welded with the rear plate and extends from the rear plate toward the face plate, and a distal end portion jointed to the extending end of the support body and being in contact with the face plate.
