A color image receiving tube comprising three color (red, green and blue) phosphor screens on an inner surface of a face-plate; wherein at least two of said three color phosphor screens are coated with pigments; and wherein said three color phosphor screens have a total reflective brightness less than 70% that of three color phosphor screens with no pigment coating. According to the above-mentioned constitution, a color image receiving tube having a higher emisson brightness and contrast is achieved as compared to a color image receiving tube having the same reflective brightness, where the reflective brightness is obtained by lowering the light transmittance of its face-plate.

On the outer surface of the glass face panel 2 of a display device, a first layer 5 of an electrically conductive transparent thin film, a second layer 6 of another transparent thin film consisting essentially of silicon dioxide (SiO.sub.2) or magnesium fluoride (MgF.sub.2), and a third layer 7 of uneven exposed surface, are deposited, whereby a multiplicity of concave regions of said third layer 7 form an interference film together with said first 5 and second layer 6, whereas a multiplicity of convex regions of said third layer form an irregular reflection surface.
