Abstract
An explosion-proof film being good in visibility, scratch-resistance, and workability, and a cathode-ray tube using the film. The explosion-proof film includes a transparent plastic film as a base material; and a reflection preventive film having two or more layers, which is formed on one surface of the plastic film; wherein, of the two or more layers of the reflection preventive film, at least one has a light absorption function, and at least another has a conductive function. The explosion-proof film is stuck on a surface of a panel glass constituting a display screen of a cathode-ray tube, to thereby give an explosion-proof function to the cathode-ray tube, to achieve lightweightness of the cathode-ray tub, and to obtain the optimum visual contrast. The explosion-proof film may be formed of three or more layers.
