A funnel structure of a CRT in which provided that a deflection angle is 110° or more, a length of an outer surface evaluation line formed by connecting a TOR outer surface end where the funnel yoke portion and the funnel body portion meet and a neck seal outer surface end where the funnel yoke portion and the neck portion meet by a straight line is ‘a’ and a length of a straight line from the outer surface evaluation line where a vertical distance between the funnel yoke portion outer surface and the outer surface evaluation line is maximized, to the neck seal outer surface end is ‘b’, a formula of 0.20≦b/a≦0.40 is satisfied, so that a sensitivity of a deflection yoke is improved and a beam shadow neck margin of the electron beam can be satisfied.
A funnel structure of a cathode ray tube having a panel with a fluorescent screen inside thereof, a funnel sealed to the panel in a vacuum state, an electron gun mounted at a neck portion of the funnel and emitting an electron beam toward the fluorescent screen, and a deflection yoke mounted at a yoke portion of the funnel and deflecting the electron beam,
A funnel structure of a cathode ray tube having a panel with a fluorescent screen inside thereof, a funnel sealed to the panel in a vacuum state, an electron gun mounted at a neck portion of the funnel and emitting an electron beam toward the fluorescent screen, and a deflection yoke mounted at a yoke portion of the funnel and deflecting the electron beam,
