Abstract
A cathode ray tube has a vacuum envelope formed of a panel portion supporting a phosphor film on an inner surface thereof, a neck housing an electron gun, a funnel joining the panel and the neck, and a stem sealing an open end of the neck and mounting the electron gun via a plurality of pins extending through the stem. The inside diameters at the open end sealed by the stem and vicinities thereof become gradually larger toward the open end sealed by the stem, or retain at least a value substantially equal to an inside diameter of a major portion of the neck.
