Abstract
a cathode ray tube comprises an envelope including a faceplate with an inner and outer surface and an antistatic layer covering the outer surface of the faceplate for discharging static charges accumulating in the faceplate. The antistatic layer is formed by using a solution containing an alcoholate of silicon as main constituent. The antistatic layer contains a stabilizing substance for maintaining antistatic characteristics. The antistatic layer also has light filtering characteristics when the layer contains xanthene dye as filtering substance.
