PURPOSE:To enable to observe the picture screen clearly without reflection or deterioration in brightness of the screen, by attaching a transparent conductive film with a grounding to the side of a flat plate opposing to the picture screen, and frosting the observing side of the plate 3. CONSTITUTION:The electromagnetic shielding body 3 consists of the plate 4 and the transparent conductive film 5 attached thereto. The plate 4 is transparent, made of clear resin plate such as acrylic resin, or glass plate if possible, has enough size to cover the picture screen 2, is placed with a given interval against the screen 2, and its observing side is frost processed. The transparent film 5 has a transparent film base material 7 and a transparent conductive membrane 8. The transparent conductive membrane 8 is grounded with a ground line E, and is preferable to be vacuum evaporated with indium tin oxide. |
