A filter 2A(2C) which prevents the leakage of electromagnetic waves from a PDP 1, and is provided with a filter base 11 in front of the PDP 1 and grounded conductive mesh 12 which transmits light on the base 11 on the PDP 1 side. Alight scattering layer 13 is bonded to the mesh 12 with a conductive adhesive 14 which transmits light, and the spaces of the lattice (when the base 1 exists) of the mesh 12 are filled with the adhesive 14 so that, when electric charge is induced in the mesh 12 by a pulse voltage applied to the PDP 1 for write/erase, the voltage across the lattice of the mesh 12 is made nearly equal to the potential of the mesh 12 so as not to cause electric discharge and generate noise. Alternatively, a transparent antistatic layer 22 is provided between the PDP 1 and the mesh 12 so as not to generate noise by lowering the pulse voltage applied to the PDP 1 for write/erase to such a low value that no electric discharge occurs when electric charges are induced in the mesh 12 by the pulse voltage. <IMAGE> |
