ABSTRACT:
An electromagnetic-wave shielding and light transmitting plate suitable for an electromagnetic-wave shielding filter for a PDP, which has good electromagnetic-wave shielding efficiency and light transparency, can provide distinct pictures, and can yet be easily made, is provided. The electromagnetic-wave shielding and light transmitting plate is formed of two transparent base plates and an adhesive layer made of EVA in which conductive particles are dispersed and mixed. The base plates are integrally bonded together by the adhesive layer. Adjusting the particle size and the dispersed amount of the conductive particles enables the manufacture of plates having desired electromagnetic-wave shielding efficiency, in addition, good light transparency, without moire phenomenon. Using an adhesive sheet formed by mixing the conductive particles into the EVA facilitates the manufacture of the aforementioned plate.
