A color cathode ray tube includes a generally rectangular phosphor screen having a plurality of phosphor pixel line-trios each formed of three color phosphor pixels arranged in a line and a black matrix of opaque material having holes for defining areas of the phosphor pixels which are viewed through a panel, a shadow mask having a large number of mask apertures for color selection, and an electron gun. A distribution in area of center phosphor pixels of the phosphor pixel line-trios has sharp decreases, going from a center of the phosphor screen toward a periphery of the phosphor screen, in the vicinity of at least one of (a) top and bottom sides and (b) right and left sides, of a rectangular useful display area of the phosphor screen.
