Abstract: PROBLEM TO BE SOLVED: To provide a color cathode-ray tube with an enhanced image grade by preventing deterioration in color purity owing to beam landing displacement caused by deformation or doming of a shadow mask. SOLUTION: A panel is equipped with a substantially rectangular effective part having a substantially flat outer surface, and a phosphor screen is formed on an inner surface of the effective part. The shadow mask disposed opposite to the phosphor screen has a substantially rectangular mask body with a multiplicity of electron beam passing holes formed therein and a mask frame for supporting peripheral parts of the mask body. Spaces between passing holes along the major axis X direction of the mask body increase from the center of the mask body toward the ends of the major axis, and the rate of change of spaces between passing holes has a maximal value between the center of the mask body and each end of the major axis.

Abstract: PROBLEM TO BE SOLVED: To reduce deterioration of color purity caused by doming of a shadow mask when actuated and deformation of a mask body in a manufacturing process, by forming an effective surface of the shadow mask body into a curved surface having specified curvatures for a long axis direction and a short axis direction. SOLUTION: The effective surface 27 of the mask body 29 of a shadow mask 31 in a color picture tube has a curved surface having a curvature of 0-2×104 (1/mm) from the center of the effective surface 27 to the intermediate part in its long axis direction (X axis), a bigger curvature in its peripheral part than one in the intermediate part and a curvature in its short axis direction (Y axis) gradually and continuously growing up to at least 2/3 of the distance from the center of the effective surfaces 27 to the end of the effective diameter of the short axis. Thereby, curved surface holding strength of the shadow mask 31 is enhanced, and since deformation of the effective surface 27 of the mask body 29 can be suppressed, deterioration of color purity caused by a slippage of beam landing onto a three color phosphor layer can be reduced.
