Abstract
A cathode ray tube includes a panel having an inner phosphor screen, and a funnel having a panel sealing side, a cone portion and a neck sealing side. The panel sealing side of the funnel is sealed to the panel at a phosphor screen-side. A deflection yoke is mounted around the cone portion of the funnel. A neck is sealed to the neck sealing side of the funnel and an electron gun is mounted within the neck. The cone portion of the funnel is formed with a sectional shape where a circle gradually changes into a non-circle from a neck-side of the cone portion to a panel-side of the cone portion. The cone portion of the funnel has a thickness in a horizontal axis direction and a thickness in a diagonal axis direction, and the ratio of the diagonal thickness to the horizontal thickness ranges from 1.03 to 1.21.
