<p>A cathode ray tube prevented from imploding by the use of a clamping band. The cathode ray tube has a panel (21) composed of a face portion (4) and a skirt portion (5). A mold match line (23) of the panel (21) is formed such as to be substantially coincident with the boundary between the face portion (4) and the skirt portion (5). A clamping band (29) for implosion prevention is wound on the panel (21) along the mold match line (23). By so doing, the clamping force of the clamping band is effectively transmitted to the entire periphery of the face portion, whereby the implosion-proof strength of the panel is increased.</p> |
