    • Transparent laminates which have high transparency and, moreover, excellent electromagnetic shielding characteristics and near-infrared cutting-off characteristics, and optical filters for displays using these transparent laminates. These transparent laminates are formed by laminating a transparent electrically conductive layer composed of high-refractive-index transparent film layers (B) and metal film layers (C) consisting of silver or a silver-containing alloy on one major surface of a transparent substrate (A) in such a way that a repeating unit comprising a combination of one high-refractive-index transparent film layer (B) and one metal film layer (C) is laminated three times or more, and further laminating one high-refractive-index transparent film layer (B) thereon. The transparent laminate has a sheet resistance of not greater than 3 .OMEGA./sq., a visible light transmittance of not less than 50%, and a light transmittance of not greater than 20% in a wavelength region longer than 820 nm. Optical filters for displays which serve to block leakage electromagnetic waves and near-infrared light from plasma displays can be acquired by using such a transparent laminate.
    • 具有高透明度,以及优异的电磁屏蔽特性和近红外截止特性的透明层压板以及使用这些透明层压板的显示器用滤光器。 这些透明层压体通过在透明基板的一个主表面层叠由高折射率透明膜层(B)和由银或含银合金构成的金属膜层(C)构成的透明导电层而形成, A),使得包含一个高折射率透明膜层(B)和一个金属膜层(C)的组合的重复单元被层叠三次以上,并且进一步层叠一个高折射率 透明膜层(B)。 在820nm以上的波长区域中,透明层叠体的薄层电阻不大于3欧姆/平方厘米,可见光透射率不小于50%,透光率不大于20%。 用于阻挡泄漏电磁波的显示器的滤光器和等离子体显示器的近红外光可以通过使用这种透明层压板来获得。
