  • Patent number: 4664479
    Abstract: A non-glaring type reflector employing a liquid crystal layer which is composed of a liquid crystal matrix and dichroic coloring matter, which provides a dynamic scattering effect or phase transition effect by applying an electric field. Except on the non-glaring operation, the molecular orientation of the liquid crystal matrix and dichroic coloring matter is uniform to cause a transparent state. On the non-glaring operation, however, the molecular orientation is random, thereby scattering the incident light by the liquid crystal matrix. The scattered light is then absorbed by a dichroic coloring matter to result in a decreased reflectance. The reflectance is controlled by applying a voltage into a liquid crystal layer.
