Color cathode ray tube having deformation-resistant shadow mask

A color cathode ray tube having a substantially rectangular panel part on the inside surface of which is formed a phosphor layer, and a neck part housing electron guns, a vacuum vessel having a funnel part connecting the neck part and the panel part, a main surface having a plurality of electron beam apertures and disposed opposite the phosphor layer, a substantially rectangular shadow mask having a skirt part bent from the outside circumference of the main surface toward the neck part, a mask frame for supporting the shadow mask, and comprising:

• a plurality of recessed parts in the shadow mask skirt part, the dimension of said recessed parts in the outside circumference direction of the main surface being greater that the dimension in the neck part direction,
• a shape of the recessed parts different from the electron beam aperture shape,
• the recessed parts arranged in rows in the outside circumference direction,
• a plurality of said recessed part rows being disposed in the neck part direction, and
• in adjacent rows of recessed parts, a position of recessed parts in one row is offset in the circumference direction from the position of recessed parts in the other row.
