    • A shadow mask for a cathode ray tube is formed with a curved surface such that a radius of curvature corresponding to a perpendicular axis which passes through the center of the shadow mask decreases monotonely along the perpendicular axis from the center of the shadow mask and a radius of curvature corresponding to a parallel axis which passes through the center of the shadow mask decreases monotonely along the parallel axis from the center of the shadow mask. The curved surface satisfies the following condition, [0.1RVmin+0.9RVmax, 0.9RVmin+0.1RVmax]⊂[RHmin, RHmax]. RVmin and RVmax respectively represent the minimum and the maximum value of the minimum radius of curvature corresponding to the perpendicular axis, and RHmin and RHmax respectively represent the minimum and the maximum value of the minimum radius of curvature corresponding to the parallel axis.
