An active matrix-type liquid crystal device is constituted by a pair of substrates, a chiral smectic liquid crystal composition disposed between the pair of substrates so as to form a plurality of pixels, and a plurality of active elements provided to the pixels, respectively, for driving the liquid crystal device in a matrix driving scheme. The chiral smectic liquid crystal composition may preferably comprise at least two specific fluorine-containing mesomorphic compounds and assume two stable states between which a threshold voltage for switching from one of the two stable states to the other stable state is different from a threshold voltage for switching from the other stable state to said one of the two stable states and liquid crystal molecules of the liquid crystal composition change their alignment states so as to provide a halftone state depending on a voltage applied to the chiral smectic liquid crystal.
