Abstract: A cathode ray tube capable of reducing the doming amount and suppressing the occurrence of moire stripes at the same time with improved effects to suppress the occurrence of moire stripes even more is provided. The protruding portions 28a, 28b are protruding from the ends of the horizontal direction of the aperture to the inside of the aperture 27. With regard to the horizontal cross sections of the protruding portions 28a, 28b, the portions facing each other left and right via the aperture are formed to be asymmetrical to the center line 29 in order to reduce or block the incident electron beam. By forming the protruding portions 28a, 28b, the doming amount can be reduced and the occurrence of moire stripes can be suppressed at the same time. Furthermore, by forming the portions facing each other left and right of the protruding portions asymmetrically, the effects to suppress the occurrence of moire stripes can be improved even more.

Abstract: A cathode ray tube includes a pair of plate members (7) facing each other, a pair of supporters (14) adhered to the respective plate members (7) to support the plate members (7), and a shadow mask (6) adhered to the respective plate members (7) while being applied with tensile force. The supporters (14) have crank-shaped steps (15) formed to protrude toward the shadow mask (6). Thereby, an internal moment of a shadow mask structure can be decreased, and thus, displacement of the shadow mask (6) in the axial direction is suppressed even when the shadow mask (6) is expanded by heat generated by impact of electron beams, and q-value deviation is suppressed as well. Moreover, since the crank-shaped steps (15) are helpful in blocking a transverse clearance with a ferrous material, the magnetic properties can be improved.

Abstract: A cathode ray tube capable of preventing incorrect hitting of color electron beams caused by the local doming phenomenon and the initial 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 includes a shadow mask made of a flat plate in which a number of apertures 2 are arranged in lines, and slits 5, 6 are formed in the line direction of the apertures 2. These slits 5, 6 have inclined faces 8, 9, 11 and 12 opposed via openings 10, 13. Due to this configuration, the displacement of apertures due to the local doming phenomenon or the initial doming phenomenon caused by the thermal expansion of the shadow mask can be suppressed. Thus, displacement of colors, unevenness in colors, and deterioration of luminance caused by incorrect hitting of electron beams can be prevented from occurring.
