ABSTRACT:
The present invention provides a light-transmitting electromagnetic wave-shielding material for use in displays or in-vehicle panels each having a polarizing plate or a retardation plate, wherein the light-transmitting electromagnetic wave-shielding material undergoes no generation of light interference fringes and is satisfactory in visibility even through sunglasses, goggles, glare-proof panels or glare-proof window materials having polarizing capability. By using unstretched light-transmitting organic polymer materials low in molecular orientation or small in molecular orientation unevenness as the base substrate of an electromagnetic wave-shielding layer, the light-transmitting electromagnetic wave-shielding material excellent in light interference fringe prevention capability can be obtained.
