摘要:
Provided are an optical filter for reducing duplicated images and a plasma display panel employing the same. The optical filter includes a transparent substrate, a selective absorption layer deposited on a surface of the transparent substrate, an anti-reflection layer deposited on the selective absorption layer, an electromagnetic wave shield layer deposited on the other surface of the transparent substrate, and a duplicated image reducing layer deposited on the electromagnetic wave shield layer. When using the optical filter, external reflection and duplicated images can be reduced, thereby improving visual agreement and picture quality.

A flat panel display device includes: a substrate; an electrode composed of metal; and an adhesive layer interposed between the substrate and the electrode. The electrode of the flat panel display device has excellent conductivity. The method of manufacturing the flat panel display device includes: preparing a metal substrate; forming a metal plating substrate by forming a plating mask layer on the metal substrate; forming an electrode on the metal plating substrate; separating the electrode, which is formed on the metal plating substrate, from the metal plating substrate with a cohesive layer; placing the separated electrode on another substrate using an adhesive composition; separating the cohesive layer from the electrode; and heat treating the adhesive composition to form an adhesive layer, the adhesive layer attaching the electrode to the another substrate. This method reduces the likelihood of malfunctioning electrodes being produced and leads to reduced manufacturing costs and processing time.

Provided are an electromagnetic interference (EMI) shielding film and a plasma display device including the EMI shielding film. The EMI shielding film includes: an adhesive layer formed on a transparent substrate; a metal pattern formed on the adhesive layer; and a transparent selective light absorbing layer containing a transparent material and a tetraazaphorpyrin compound, which is a selective light absorbing material, and filling the space in the metal pattern on the adhesive layer. The EMI shielding film provides improved color gamut, contrast and thermal stability. Since the EMI shielding film can shield EMI and improve the color gamut, the numbers of binding processes and other additional processes in the manufacturing of filters are reduced. In addition, the EMI shielding film can be directly and easily attached to a panel of a plasma display device.

Provided are an essentially lead-free black ceramic composition for a filter, a filter formed using the same, and a flat display device including the filter. The lead-free black ceramic composition may include at least one compound selected from the group consisting of B2O3, BaO, and ZnO; and at least one black pigment selected from the group consisting of TiO, CuO, NiO, MnO2, Cr2O3 and Fe2O3. Alternatively, the lead-free black ceramic composition may include Bi2O3; at least one compound selected from the group consisting of B2O3, SiO2, P2O5, Na2O3, Al2O3, BaO, ZnO and TiO2; and at least one black pigment selected from the group consisting of TiO, CuO, NiO, MnO2, Cr2O3 and Fe2O3. The lead-free black ceramic composition for a filter essentially does not contain PbO, which harms human beings and the environment. As a result, the use of the composition is not affected by regulations preventing the use of Pb. In addition, the composition can be calcined at a relatively low temperature and consume a small amount of energy.
