Color cathode ray tube apparatus.

摘要

In a color cathode ray tube apparatus of this invention, an electron beam forming unit of an electron gun (64) outputs electron beams to have an interval of 3.5 to 6.0 mm between adjacent beams, and a ratio of a neck inner diameter to the interval between the adjacent electron beams is 5.1 or more. The main lens unit of the electron gun has a large-aperture electron lens formed by a substantially cylindrical first electrode (GD7) for allowing three electron beams to pass therethrough, and a substantially cylindrical second electrode (GD8) in which most of the first electrode is arranged.
