ABSTRACT:
The present invention provides with a black matrix, a phosphor screen, and a method of manufacturing thereof. For a method of manufacturing the black matrix formed on the inner surface of a panel of a color CRT, a photoresist is not used, but a wet electrophotographic method was employed, using graphite for a main component of the black matrix materials, and forming a phosphor screen by a dry electrophotographic method to improve the quality of a color cathode-ray-tube.
