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.
Claims15
A cathode-ray tube having an explosion-proof film, comprising:
- a panel glass;
- an organic polymer film, having a front surface and a back surface, wherein the entire back surface is adhered to said panel glass;
- and
- a reflection preventive film having two or more layers, which is formed on said front surface of said organic polymer film;
- wherein, at least one of said two or more layers of said reflection preventive film has a light absorption function.
A cathode-ray tube having an explosion-proof film, comprising:
- a panel glass;
- an organic polymer film, having a back surface stuck directly on said panel glass, and a front surface;
- and
- a reflection preventive film having three or more layers, which is formed on said front surface of said organic polymer film;
- wherein, of said three or more layers of said reflection preventive film layer, at least one has a light absorption function, at least another has a conductive function, and at least the third is a dielectric layer.
