摘要： A color cathode ray tube includes an evacuated envelope formed of a panel portion having a phosphor screen, a neck portion and a funnel portion connecting the panel portion and the neck portion, and an in-line electron gun housed in the neck portion. The in-line electron gun includes a main lens and an electrostatic quadrupole lens. The focus electrode of the electron gun has a single opening at one end thereof for passing the three electron beams and opposes an anode to form a main lens therebetween. The single opening has a diameter larger in a horizontal direction than a diameter thereof in a vertical direction. A distance from the main lens to the phosphor screen is not larger than 300 mm, an outer diameter T of the neck portion housing the in-line electron gun satisfies the following inequality: 23.2 mm.ltoreq.T.ltoreq.25.9 mm, and a value D of twice a distance from a center of a trajectory of a side electron beam of the three electron beams to a horizontal edge of the single opening satisfies the following inequality: 5.0 mm.ltoreq.D.ltoreq.6.5 mm.

摘要： A color cathode ray tube includes an evacuated envelope formed of a panel portion having a phosphor screen on an inner surface thereof and housing a shadow mask, a neck portion and a funnel portion connecting the panel portion and the neck portion, and an in-line electron gun housed in the neck portion. The in-line electron gun includes a main lens and an electrostatic quadrupole lens. The focus electrode of the electron gun has a single opening at one end thereof for passing the three electron beams and opposes an anode to form a main lens therebetween. The single opening has a diameter larger in a horizontal direction than a diameter thereof in a vertical direction. A distance from the main lens to the phosphor screen is not larger than 300 mm, a vertical mask aperture pitch on a vertical center line of the shadow mask is not larger than 0.28 mm at a center of the shadow mask, and an outer diameter T of the neck portion housing the in-line electron gun satisfies the following inequality 23.2 mm≦T≦25.9 mm, and a value D of twice a distance from a center of a trajectory of a side electron beam of the three electron beams to a horizontal edge of the single opening satisfies the following inequality 5.0 mm≦D≦6.5 mm.
