PROBLEM TO BE SOLVED: To reduce the weight of a cathode-ray tube by forming an explosion- proof film excellent in visibility, workability and resistance to scratch. SOLUTION: Reflection preventing films 4 and 5 having two or more layers are formed on one side of a film made of an organic polymer. An explosion- proof film 6 is constituted by adding a light absorbing function to at least one layer in the reflection preventing films 4 and 5, or by adding a conducting function to at least the other layer therein. A first reflection preventing film 4 is formed on a transparent plastic film 3 acting as a base material. Moreover, a second reflection preventing film 5 is formed on the first reflection preventing film 4. The explosion-proof film 6 composed of the plastic film 3, the first reflection preventing film 4 and the second reflection preventing film 5 is affixed on the surface of a panel glass 2, namely, on the display surface of a cathode- ray tube 1 to carry out an explosion-proof function in the cathode-ray tube 1, to reduce the weight of the cathode-ray tube 1, and to present an optimum contrast from a visual point of view. This explosion-proof film 6 may be formed having three or more layers.
Abstract:
PROBLEM TO BE SOLVED: To obtain a display which prevents leakage and charging of an electro- magnetic field and prevents reflection or the like owing to outside light by a method wherein a contact terminal of a conductor such as an eyelet is pinchingly attached to one end of a functional film, and brought in contact with a conductive film by breaking a part of a non-conductive film. SOLUTION: A functional film 1 is calked by pinching that to form a contact terminal 2. A surface of the contact terminal, especially a surface in contact with a non conductive film of the functional film 1 is preliminarily roughened by a method of sand blasting, etching, etc., of a plurality of projections are formed with a press machine. The eyelet strongly pushes both sides of the functional film. When they are calked, since an AR film of the most exterior layer of the functional film 1 is a very thin film of about 100nm, the AR film and the conductive film are broken with a coarse surface of the eyelet, a projection, or a part of an end part of the eyelet, which come in contact with the conductive film on the broken out section, and the eyelet keeps continuously a deformed state.
