Claims (1)

[Scope of Claim for Utility Model Registration] A system comprising two transparent plates sandwiching a nematic liquid crystal with negative dielectric anisotropy, and by applying a voltage between the transparent electrodes provided on each of the two transparent plates. In the liquid crystal cell in which the dynamic scattering mode of the liquid crystal occurs, the liquid crystal molecules of the liquid crystal are initially aligned so that the long axes of the liquid crystal molecules are parallel to the two transparent plates, and the liquid crystal is provided with: A liquid crystal cell characterized by containing a dichroic dye whose light absorption spectrum differs depending on the direction of its molecules.
