Abstract

PURPOSE:To improve the picture quality and to reduce the power consumption, by forming the neck part of a glass tube into oval or elongated circle cross-section made of two arcs while forming the funnel portion into oval cross-section made of three arcs. CONSTITUTION:The glass tube of a color cathode-ray tube equipped with single electron gun 3 electron beam is constructed by connecting a funnel part 12 having oval cross-section made of three arcs smoothly with a neck part 11 having oval cross-section made of two arcs and an electron gun is placed in said neck part 11.
