    • A cathode ray tube capable of reducing the doming amount and suppressing the occurrence of moire stripes at the same time, which also can prevent the so-called persimmon stone phenomenon from occurring, is provided. In the apertures, the protruding portions that are protruding from end faces in the horizontal direction of the apertures to the inside of the apertures are formed. The protruding portion in the aperture located on the right side of the phosphor surface from the vertical center line of the shadow mask is protruding in the direction toward the peripheral portion on the right side, while the protruding portion in the aperture located on the left side of the phosphor surface is protruding toward the peripheral portion on the left side. Accordingly, the doming amount can be reduced and the occurrence of moire stripes can be suppressed at the same time, while the persimmon stone phenomenon in which the beam spot of an electron beam on the phosphor surface is cut partially can be prevented from occurring.

    • A color cathode-ray tube that can attenuate vibration of an entire shadow mask positively with a simple structure. The color cathode-ray tube includes a frame-shaped mask frame and a shadow mask in which many apertures are formed in a flat plate, the shadow mask stretched and fixed in the mask frame in a condition in which a tension force is applied in one direction. The amplitude in the end portions of the shadow mask is not less than a certain amount relative to the amplitude in the center portion of the shadow mask, in a resonance of the shadow mask caused by a vibration propagated to the color cathode-ray tube. Furthermore, by providing vibration attenuators at the end portions of the shadow mask, vibrations at the end portions of the shadow mask are attenuated as the side surfaces of the shadow mask slide on the vibration attenuators. Thus, vibration of the entire shadow mask can be extinguished positively.

    • Due to a slit formed in the dead space, a cathode ray tube capable of preventing incorrect hitting of color electron beams caused by the local doming phenomenon from occurring and thus preventing displacement of colors, unevenness in colors, and deterioration of luminance from occurring is provided. The cathode ray tube comprises a shadow mask having an effective area where lines of apertures for passing electron beams are arranged and a dead space formed on both outer sides of the effective area. In the dead space, a slit extending along the lines of the apertures is formed. Accordingly, the thermal expansion of the dead space caused by a temperature increase can be reduced, and the stress applied to the aperture line of the effective area adjacent to the dead space can be suppressed. As a result, the local doming phenomenon can be prevented from occurring.

    • The color cathode ray tube according to the present invention can improve the brightness without compromising strength by making the bridge width in one-dimensional tension type shadow mask narrower to a certain degree. The color cathode ray tube has a color selection electrode, the color selection electrode including a pair of supports facing each other; a shadow mask provided with a plurality of slot apertures, the shadow mask being stretched and fixed by the pair of supports; and elastic members arranged between the supports, and holding the supports. Bridges between vertically adjacent slot apertures are formed on the shadow mask. Defining the bridge width W as the largest vertical width of a bridge, the narrowest bridge width Wmin is in a range of 3-10% of a vertical pitch of the slot apertures. With this configuration, the necessary strength can be ensured, and the brightness can be improved without compromising strength, because the bridge widths W can be made narrower.
