    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.

    摘要： A liquid crystal display element has a liquid crystal cell contructed such that a liquid crystal layer composed of a liquid crystal composition having a positive dielectric anisotropy is homogeneously oriented between a pair of substrates provided with electrodes; a pair of polarizers disposed such that the liquid crystal layer is arranged between the polarizers; and a uniaxial medium disposed at least one of clearances between the liquid crystal layer and the both polarizers, the uniaxial medium having a positive optical anisotropy and an optical axis in a direction perpendicular to a substrate face. In the liquid crystal display element, products of refractive index anisotropy and thickness of the uniaxial medium are different from each other in accordance with the difference between displayed colors determined every display picture element.
