Abstract
A cathode ray tube has an envelope including a faceplate with a sidewall portion and a neck receiving an electron gun emitting at least one electron beam. The faceplate is coated with a phosphor layer for emitting a visible light by bombardment of the electron beam on its inner surface and is covered with an antistatic film. To prevent accumulation of electrostatic charges, the antistatic film is electrically connected to a metal tension band wound around the sidewall portion by a connecting element. The connecting element is conductive oxide layer which essentially consists of a conductive substance and a binder consisting at least amorphous silicon oxide or silicon hydroxide.
