摘要： The invention provides a light modulating material capable of supplying a predetermined light modulating property over a long period of time regardless of an incident light condition. The light modulating material includes at least: a first liquid crystal layer which has at least a dichroic dye and changes from a colorless transparency state to a colored transparency state when voltage is applied thereto; and a second liquid crystal layer which changes from a colorless transparency state to a white light-scattering state when voltage is applied thereto. The second liquid crystal layer is provided closer to a surface of the light modulating material on which light is incident compared to the first liquid crystal layer.
摘要翻译：本发明提供一种光调制材料，能够长时间地提供预定的光调制特性，而与入射光条件无关。光调制材料至少包括：当施加电压时至少具有二色性染料并从无色透明状态变为着色透明度状态的第一液晶层; 以及当施加电压时，从无色透明状态变为白色光散射状态的第二液晶层。与第一液晶层相比，第二液晶层更靠近光入射的光调制材料的表面。
