Abstract:
A liquid crystal device including a pair of electrodes provided with a vertical alignment film and a liquid crystal layer disposed between the pair of electrodes and including a liquid crystal composition containing a liquid crystal with positive dielectric anisotropy, a dichroic dye and a chiral reagent, with a ratio (P/G) of a chiral pitch length (P) of the liquid crystal composition to a gap (G) between the pair of electrodes being from 0.06 to less than 1.0.
