An image display device having a vacuum envelope which has a light transmissible
panel, a funnel and a neck, its inside held vacuum, a phosphor layer is formed
on the inside surface of the light transmissible panel, an electron gun is disposed
within the neck. An antistatic film which contains high-resistance fine particles
having a specific resistivity of 106 to 109 cm
is formed on inside wall of the neck. The image display device is free from deterioration
of display characteristics caused by a change of the track of electrons emitted
by the application of voltage, a spark in a tube, or a leakage current.
