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： The radius of curvature of the outer surface of a panel is 10,000 mm or more, and a shadow mask is made of a material containing 95% or more of iron. A sagging amount change curve along a curve C1 on the surface of the shadow mask, which a plane passing through a center P0 of a useful area of the shadow mask and parallel to a tube axis and a major axis crosses, satisfies a particular Condition 1. Assuming that an intersection between the curve C1 and a useful area end of the shadow mask is a major axis end PL, a distance from the center P0 to the major axis end PL along a major axis is W, and a point on the curve C1 away from the center P0 by ⅔×W in the major axis direction is P1, a sagging amount change curve along a curve C2 on the surface of the shadow mask, which a plane passing through the point P1 and parallel to the tube axis and the minor axis crosses, satisfies a particular Condition 2. Consequently, a color picture tube can be realized, which has satisfactory visibility, and less degradation in color purity caused by doming while having a shadow mask made of an inexpensive material with satisfactory moldability.
