Color cathode ray tube

Abstract

A color cathode ray tube is disclosed, in which brightness is excellent, uniformity of brightness is improved, and characteristics of contrast are improved. To this end, the color cathode ray tube includes a panel (1) having an inner surface on which an electron bean emitted from an electron gun is irradiated and an outer surface exposed outwardly; black matrixes (10) formed at the inner surface of the panel (1) with a predetermined interval; a fluorescent film (20) composed of red, green, and blue fluorescencers among the black matrixes (10); and a black filter film (30) formed at the outer surface of the panel (1), or between the inner surface of the panel (1) and the fluorescent film (20), or between the inner surface of the panel 1 and the fluorescent film (20) with covering the black matrix (10).
