    摘要： A ferroelectric liquid crystal device comprises a pair of substrates each provided with an electrode, and a ferroelectric liquid crystal disposed between the pair of substrates. At least one of the pair of substrates has thereon an inorganic oxide layer which has a resistance of 1-10.sup.5 .OMEGA./cm.sup.2 in the direction of the layer thickness and preferably has a pencil hardness of 4H or harder. Because of the provision of the inorganic oxide layer, the ferroelectric liquid crystal device shows good bistability on switching under application of pulse electric fields and yet free of short circuit between the upper and lower electrodes.

    摘要： A ferroelectric smectic liquid crystal device having an improved impact resistance and an improved contrast is provided by using a pair of substrates provided with uniaxial alignment axes which are parallel and identical in direction with each other. A ferroelectric smectic liquid crystal is disposed between the pair of substrates so as to assume a higher-temperature alignment state and a lower-temperature alignment state on temperature decrease in its ferroelectric smectic phase placed in a bistable alignment state. The ferroelectric smectic liquid crystal is further placed in the lower-temperature alignment state which is characterized by having an inclination of forming a connected pair of a lightning defect and a hair pin defect coming after the lightning defect.
