A cathode ray tube includes a panel with a sealing surface, and a funnel with a sealing surface contacting the sealing surface of the panel. The panel and the funnel each have a thickness varied at the sealing surface thereof.

Cathode ray tube

A cathode ray tube includes a panel with inner and outer surfaces, a funnel connected to the panel, a neck connected to the rear of the funnel, and a shadow mask mounted within the panel. The inner surface of the panel satisfies the following condition:0.2&#x2266;Px&#x2266;0.4, 0.3&#x2266;Py&#x2266;0.6where when the inner surface of the panel is expressed by the following biquadratic: based on the central point of the inner surface of the panel with the three-dimensional orthogonal coordinates system defined by the x, y and z axes, Px and Py are defined by the following formula: 

A tension mask frame assembly of a color CRT includes a tension mask in which a plurality of electron beam passing holes are formed and a frame. The frame includes a pair of first and second support members separated a predetermined distance from each other and supporting the tension mask so that a tensile force is applied to the tension mask. First and second elastic members are installed between both end portions of each of the first and second support members, supporting the first and second support members to be separated a predetermined distance from each other to compensate for an amount of thermal expansion of the tension mask, and having inclined portions inclined at a predetermined angle. Bars connect the first and second support members and are made of a material having a thermal expansion coefficient smaller than that of the first and second elastic members.
