摘要： The radius of curvature of an outer surface of a useful portion of a panel is 10,000 mm or more, and a shadow mask is made of a material containing 95% or more of iron. Assuming that a distance (unit: mm) along an X-axis between a center of the panel and a peripheral edge of the useful portion is LH, and a total number of rows of apertures composed of electron beam passage apertures arranged on a straight line substantially parallel to a Y-axis is N, 0.9≦LH/N≦1.0 is satisfied. Furthermore, assuming that a pitch of adjacent rows of apertures is PHC at a center of a perforated region of the shadow mask, PHH at a major axis end of the perforated region, and PHM at a point away from the center of the perforated region by 2/3 of a distance MH between the center of the perforated region and the major axis end along the X-axis, PHM/PHC≦1.2 and PHH/PHC≦1.4 are satisfied. Because of this, a color picture tube can be provided, which has satisfactory visibility, has less degradation in color purity due to doming while having a shadow mask made of an inexpensive material with satisfactory formability, and is excellent in uniformity of brightness.

摘要： A deflection yoke on a yoke mounting portion with a truncated pyramid shape has a pair of saddle-type horizontal deflecting coils that is located symmetrically with a central axis and has a truncated pyramid shape. A core with a truncated cone shape is coaxially located on the outer periphery of the horizontal deflecting coils. A pair of vertical deflecting coils are toroidally wound around the core. If the positions of a horizontal axis and a vertical axis are given by 0° and 90°, respectively, in the circumference direction around the central axis, the winding of one vertical deflecting coil has a starting point on the horizontal-axis side within the range of 5°-30° and is distributed from the starting point to 90° and wound symmetrically with the vertical axis. The windings of the vertical deflecting coils are wound symmetrically with the horizontal axis.

摘要： A shadow mask opposed to a phosphor screen has a substantially rectangular effective surface (30) where slit-like apertures are formed. The apertures are disposed so as to constitute a plurality of aperture rows which extend in parallel with the short axis of the effective surface and are disposed in the long axis of the effective surface. Each of the aperture rows includes a plurality of aperture, and bridges (38) positioned between any adjacent pair of the apertures. The width B of the bridges in the lengthwise direction of the aperture rows, positioned an intermediate between the short axis of the effective surface and a short side edge thereof is greater than that of the bridges positioned at a peripheral portion of the effective surface.
