Abstract:
A color cathode ray tube having a reinforcing band, which constricts the outer periphery of a skirt portion of a vacuum envelope, arranged so as to fulfill a relation, b≧2.0a, where a is the distance between first and second planes along a tube axis, the first plane intersecting an end edge of the skirt portion and extending perpendicular to the tube axis, the second plane containing the central axis of stud pins supporting a shadow mask and extending perpendicular to the tube axis, and b is the distance between the first plane and a third plane along the tube axis, the third plane intersecting a side edge of the reinforcing band facing a vacuum envelope funnel.
