Abstract
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 Ω·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.
