  • Publication number: 20040041513
    Abstract: An internal magnetic shield is joined to a color selection electrode structure including a color selection electrode, a pair of longer side frames supporting the color selection electrode with tension being applied and a pair of shorter side frames joined to the pair of longer side frames. Magnetic shielding members inclined at an inclination angle &thgr; (&thgr;≠0°) to a tube axis are provided on lateral surfaces of shorter sides of the internal magnetic shield. Phosphor screen side edges of the magnetic shielding members are located between the color selection electrode and a plane that passes through color selection electrode side ends of the pair of shorter side frames and is perpendicular to the tube axis. In this manner, magnetic shielding characteristics can be improved against not only a transverse magnetic field but a tube axis magnetic field.
