    摘要: A subject for the invention is to provide an electromagnetic-shielding light-diffusing sheet which has satisfactory electromagnetic shielding performance, attains a large transmitted-light amount, and can emit even diffused light having reduced unevenness of luminance. The invention relates to an electromagnetic-shielding light-diffusing sheet comprising a light-diffusing sheet main body and, laminated on at least one side thereof, a light-transmitting electroconductive layer having a surface resistivity of 105 Ω/□ or lower.
