ABSTRACT:
A color cathode ray tube with reduced desquamation includes a panel on which spaced-apart phosphor elements and a black matrix, filling the spaces between and contacting the phosphor elements, are disposed. A metal back covers the phosphor layer and the black matrix and is in direct contact with the black matrix and is spaced from and does not contact the phosphor elements. The direct contact with substantially all the black matrix and the complete separation from the phosphor elements improves the adhesion of the metal back while increasing luminance and reducing desquamation of the metal back.
