| Zusammenfassung: | PURPOSE: A color cathode ray tube is provided to control a transmissivity and achieve improved contrast by mixing a carbon black or titanium black and blue, green, and red pigments to the composition of coating to be deposited on the outer surface of a panel. CONSTITUTION: A color cathode ray tube comprises a panel having an inner surface on which a screen is formed; a funnel mounted on the rear surface of the panel; and one or more coating films of anti-charge conductive films and anti-reflection protective film deposited on the outer surface of the panel. The single or multi-layer coating film is made of a material having a maximum absorption peak at 480 to 500nm and 600 to 620nm. |
