が検討されている。[0003] Since a PDP utilizes a light emission phenomenon accompanying gas discharge, a large current flows and a magnetic field is generated.
For this reason, there is a concern that the electromagnetic waves generated from the PDP may affect the human body and other electronic devices. For this reason,
Attachment of an electromagnetic wave shielding filter to a PDP has been studied.

要がある。The basic structure of a DC type PDP is to selectively discharge and emit phosphors in a large number of display cells separated between two glass plates, and a partition is provided between a front glass and a rear glass. A display cell, an auxiliary cell, and the like are arranged, and a red phosphor, a green phosphor, and a blue phosphor are provided in a film on the inner wall of each display cell. These phosphors emit light when discharged by the voltage applied to the cathode, display anode, and auxiliary anode. For this reason, it is inevitable that electromagnetic waves of several kHz to several GHz are generated from the front surface of the PDP due to voltage application, discharge, light emission, and the like, and it is necessary to shield the electromagnetic waves.

ている。For this reason, conventionally, a transparent filter having an electromagnetic wave shielding function is disposed on the front surface of the PDP in order to shield electromagnetic waves from the PDP. That is, the filter used to prevent the leakage of the electromagnetic waves has a configuration in which a conductive mesh material such as a wire mesh is interposed between transparent substrates such as an acrylic plate to be integrated.

あれば導電性メッシュを用いることを要さない。However, in terms of simplifying the manufacturing process, reducing the manufacturing cost, and improving the production efficiency, it is more advantageous to use a transparent conductive film than to use a conductive mesh as an electromagnetic wave shielding material. The use of a conductive mesh is not necessary as long as it is a multilayer film in which a certain kind of transparent oxide conductive film and a metal thin film are alternately laminated.

However, the filter proposed here has a drawback that the transparent conductive film has a sheet resistance of 3Ω / □ or less, and therefore has a low visible light transmittance and a high reflectance.

The adhesive resin or the adhesive resin is 0.0%
The present invention relates to a plasma display filter comprising 5% by weight or more of a metal deactivator, and more specifically, a transparent conductive film layer is formed on a transparent resin substrate,
This is a plasma display filter in which an antireflection film is laminated on this film with an adhesive or a pressure-sensitive adhesive containing a metal deactivator.

Because the sheet resistance of the sheet is a transparent conductive film larger than 3Ω / □,
While having electromagnetic wave shielding properties, high visible transmittance,
The reflectivity can be reduced.

ことができる。As the transparent conductive film to be used, a thin film of silver (or silver alloy), copper, gold, platinum or the like and a metal oxide (tin oxide, indium oxide, titanium oxide, zinc oxide, indium-tin alloy) are usually used. Oxides and the like are alternately laminated. As a transparent conductive film formed of a thin film stack, for example, a known method is proposed as proposed in US Pat. No. 4,799,745. Since such a thin film laminate shields near-infrared light by interference, it is possible to prevent leakage of near-infrared light emitted from the plasma display light-emitting panel. These transparent conductive films can be easily formed on a base film by a sputtering method, a vacuum evaporation method, an ion plating method, a CVD method, or the like.

の透過率が高くなるので10Ω/□以下がよい。In the present invention, if the resistance value of the transparent conductive sheet exceeds 3 Ω / □, the transmittance of near infrared rays of 800 to 1000 nm increases, so that it is preferably 10 Ω / □ or less.

以上である。Since the silver (or silver alloy) thin film constituting the transparent conductive film is easily oxidized relatively early, in the present invention, for example, a metal deactivator such as benzotriazole is used as an adhesive or a tackifier. The amount is 0.01% by weight or more, preferably 0.05% by weight.
That is all.

ましい。In order to reduce the leakage of electromagnetic waves, it is desirable to install metal electrodes along the four sides of the filter and make electrical contact with the conductive surface of the transparent conductive film. However, this electrode is not necessary in the case of a plasma display light-emitting panel that generates a small amount of electromagnetic waves. Even in such a case, since the transparent conductive film may be charged by the capacitor effect, it is preferable to ground at least one place from the transparent conductive film.

することにより色再現性が特に改善される。In order to further reduce the transmittance of near-infrared rays, a known near-infrared absorbing dye can be laminated by coating or kneading. Further, various dyes can be mixed in the transparent conductive film or an adhesive or a pressure-sensitive adhesive described later in order to correct the transmission color or the reflection color. In particular, for the purpose of correcting the emission color of the plasma display, it is preferable to mix a dye that selectively absorbs and blocks only light of a specific wavelength. Among them, color reproducibility is particularly improved by using a dye having a maximum absorption at 570 to 595 nm.
