PROBLEM TO BE SOLVED: To provide both sufficient electromagnetic shielding and low reflectivity at low cost for a CRT which requires high definition display performance. SOLUTION: In order to manufacture a low reflectivity electromagnetic shield film for a cathode-ray tube from a low reflective film in which a high refractive index layer 12 and a low refractive index layer 11 are sequentially laminated by a wet method on one surface of a base film (PET) 13, a low resistance conductive layer (ITO layer) 14 and an adhesive layer 15 are sequentially laminated on the other surface of the base film 13. Another low resistance conductive layer of metal oxide, metal nitride, or metal fluoride, etc. is added to compensate the low conductivity of a wet type film, resulting in an improved electromagnetic wave shielding performance. The conductive layer is preferred, considering a shielding performance, to be formed by a dry method such as sputtering, CVD, etc. COPYRIGHT: (C)2004,JPO
