<p>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 a grounded conductive mesh (12) which transmits light on the base (11) on the PDP (1) side. A light scattering layer (13) is bonded to the mesh (12) with a conductive adhesive (14) which transmits light, and the spaces of the lattice (where 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.</p> |
