Abstract
A method of manufacturing a cathode-ray tube is provided, wherein in forming a phosphor screen on the inner surface of a faceplate of the cathode-ray tube, the inner surface of the faceplate faces downward while the faceplate is rotated about the axis of the cathode-ray tube, and a liquid material for forming a film is sprayed from a supply nozzle arranged to be substantially perpendicular to the inner surface of the faceplate so as to spray the liquid material on the inner surface of the faceplate along all directions, thereby forming a uniform film throughout the inner surface of the faceplate.
