    摘要： There is disclosed a reversible recording material having a liquid crystal mixture comprising at least two cholesteric liquid crystal compounds. The cholesteric liquid crystal compounds which are contained in the reversible recording material has a molecular weight of less than 2000 and a grass transition temperature equal to or more than 30° C. The two cholesteric liquid crystal compounds are compatible each other. After at least a part of the reversible recording material is heated to a temperature where the part of the reversible recording material becomes a cholesteric liquid crystal phase, the part of the reversible recording material is rapidly cooled down to below the glass transition temperature thereof, so that a reflecting color from the reversible recording material can be fixed to achieve a recording.

    摘要： An optical deflection device includes an optical deflection element having a pair of transparent boards arranged in a mutually opposing manner. A liquid crystal layer is filled between the boards and forms a chiral smectic C phase. An orientation film orients liquid crystal molecules in the liquid crystal layer in a substantially perpendicular direction with respect to the liquid crystal layer. Electrodes generate an electric field in a substantially parallel direction with respect to the liquid crystal layer. A first voltage application part applies, to the electrodes, an ac voltage of a deflection frequency switching the optical deflection direction of the optical deflection element. A second voltage application part applies, to the electrodes, an ac voltage of a higher frequency than the deflection frequency. A stop process part causes the second voltage application part to apply the ac voltage of the higher frequency than the deflection frequency after causing the first voltage application part to apply the ac voltage of the deflection frequency, when stopping an operation of switching the optical deflection direction of the optical-deflection element.
