Abstract
A color display screen comprising a coating which contains at least a green and/or a red phosphor and at least a pigment having the composition Zn.sub.3-3x In.sub.2xy Ga.sub.2x-2xy S.sub.3, wherein 0.2<x<0.97 and 0.1<y.ltoreq.1.0, yields a high-contrast and low-reflection picture, because the solid-solution properties of the pigmentation in accordance with the invention enable its absorption properties to be accurately adapted to the emission spectrum of the phosphor. The solid solutions having the above-mentioned composition are characterized by steep absorption edges in the yellow-orange spectral range and by a high absorptivity. This permits thin pigment-containing layers and small quantities of pigment to be used.
