Color cathode ray tube apparatus

A color cathode ray tube apparatus comprising:

• an envelope having a panel, a funnel, and a neck;
• a screen formed on an inner surface of said panel;
• an electron gun, accommodated in said neck, for outputting a plurality of electron beams;
• and
• deflection means, arranged to extend from said neck to an outer surface of said funnel, for deflecting the electron beams in horizontal and vertical directions,
• wherein said deflection means comprises at least saddle-type horizontal and vertical deflection coils, the electron beams ar deflected by said deflection means to have a maximum diagonal deflection angle of not less than 100.degree., said electron gun comprises at least an electron beam forming unit having three cathodes, and a main electron lens unit for focusing and converging the electron beams, said electron beam forming unit outputs adjacent electron beams at an interval of 3.5 to 6.0 mm, a ratio of an inner diameter of said neck to the interval between the adjacent electron beams is not less than 5.1, and said main electron lens unit comprises a large-aperture electron lens formed by a substantially cylindrical first electrode for allowing three electron beams to pass therethrough, and a substantially cylindrical second electrode in which most of said first electrode is arranged.
