The display filter is constituted by laminating a transparent adhesive layer (C)containing dye, a polymer film (B), a transparent electrically conductive layer (D), a transparent adhesive layer (E), and a functional transparent layer (A)having an anti-reflection property, a hard coat property, a gas barrier property, an antistatic property and an anti-fouling property sequentially in this order, adhered on a display area; on this occasion, the transparent electrically conductive layer (D)is grounded to a ground terminal of the display via an electrodeand an electrically conductive copper foil adhesive tape

A transparent conductive laminate in which a transparent conductive layer (an ITO film) mainly comprising indium, tin and oxygen is formed on one main surface of a transparent substrate such as a polymeric film and which is excellent in moist heat resistance and scuff resistance and which can be applied to various kinds of transparent electrodes. The transparent conductive layer has a stable amorphous structure, and its resistivity is 1&times;l0 &OHgr;&middot;cm or less, and its electron mobility is 20 cm /(V&middot;sec) or more. This transparent conductive laminate can be prepared by forming an amorphous film mainly comprising indium, tin and oxygen and having a resistivity of more than 1&times;10 &OHgr;&middot;cm on the substrate by a sputtering process under a high oxygen concentration atmosphere, and then subjecting the film to a heat treatment in the range of 80 to 180&deg; C. to decrease the resistivity to 1&times;10 &OHgr;&middot;cm or less, while the amorphous structure is maintained. This transparent conductive laminate can suitably be utilized as the transparent electrode of an electroluminescence light-emitting element equipped with a layer containing zinc sulfide as a light-emitting layer, and in this case, the deterioration of luminance during continuous light emission can be remarkably inhibited.

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.

A laminate using a polymeric molded article as a substrate and having a light transparency, gas barrier properties and an excellent alkali resistance. The laminate is obtainable by carrying out a surface treatment to deposit an oxide of at least one metal selected from the metal elements of groups 2, 8, 9, 10 and 11 of the periodic table, and then forming a gas barrier layer such as oxides of silicon, nitrides of silicon and carbides of silicon on the treated surface. The gas barrier layer is not peeled off from the polymeric molded article even after being immersed in an alkali solution of pH 12 or more. The amount of the metal on the treated surface is preferably in the range of 5.times.10.sup.14 atoms/cm.sup.2 to 3.times.10.sup.16 atoms/cm.sup.2 in terms of the metal atoms per unit area. The practical performance of the laminate is not deteriorated during the patterning, by alkali etching, of a transparent conductive layer formed on the laminate.
