摘要： A cathode ray tube includes a panel having a front screen portion on which a phosphor screen is formed and a panel flange integrally formed on an edge of the front screen portion, a funnel connected to the panel flange, a deflection yoke disposed around the funnel, a neck connected to the funnel, an electron gun disposed in the neck, a color selection apparatus for selecting electron beams emitted from the electron gun and allowing the selected electron beams to land on corresponding phosphors, and an inner shield for shielding geomagnetism, the inner shield mounted on the color selection apparatus. The color selection apparatus includes a mask having a plurality of electron beam-passing apertures, the mask being rectangular and having a longitudinal axis and a lateral axis, a frame for supporting the mask in a tensioned state, and a pair of side shield members mounted on lateral sides of the frame to shield the geomagnetism.
