Abstract
A color cathode-ray tube apparatus having: a glass bulb including a face panel, a funnel, and a neck; a deflection yoke attached to the funnel to surround thereof; and a color-selection electrode disposed inside the face panel. A pair of degaussing coils are wound around the upper and lower portions of the glass bulb, respectively. A loop coil, which is disposed around the glass bulb between the color-selection electrode and the deflection yoke, includes: a first portion including two extending portions of the loop coil positioned over and below the glass bulb respectively, each center of the extending portions being substantially in a plane perpendicular to a tube axial of the glass bulb; and a second portion including two bent portions that are formed by bending right and left sides of an original form of the loop coil toward the neck.
