NOVELTY - The electromagnetic wave shielding layer (100) is provided with electroconductive patterned layer (10) formed by predetermined pattern on transparent base material (20,40). The electromagnetic wave shielding layer is provided with metal particle (1) and binder resin (2). A portion of metal particle is exposed from binder resin. The surface of metal-particle exposure portion (1m) is provided with groove-shaped recessed portion (1v) and microprotrusion (1p). The functional layer is provided on side opposite to reflection prevention layer (200) between electromagnetic wave shielding layers.    USE - Transparent electrically conductive material e.g. front installation type electromagnetic wave shielding filter for plasma display panel image display apparatus (claimed). Uses included but are not limited to TV, monitor of personal computer, cathode ray tube display apparatus, LCD apparatus, electroluminescence display apparatus, TV image receiving apparatus, measurement apparatus, measuring instrument, office machine, telephone, game equipment, electrical decoration signboard, microwave oven, window of building, vehicle, boat, aircraft and ship, transparent electrode, mobile telephone, and solar cell.    ADVANTAGE - The electromagnetic wave shielding performance and the reflection prevention performance of display apparatus can be improved with respect to the exterior light. The surface-resistance value and electroconductive fall can be suppressed. Since the metal plating process is not needed, the manufacturing cost of the display apparatus can be reduced.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for plasma display panel image display apparatus has main portion to which transparent electrically conductive material is attached.    DESCRIPTION OF DRAWING(S) - The drawings show sectional view of the electromagnetic wave shielding layer and explanatory view of the electroconductive patterned layer.
