    摘要： A liquid crystal device is constituted by a pair of oppositely disposed substrates having opposing inner surfaces and opposing electrodes thereon, and a chiral smectic liquid crystal assuming two stable states disposed between the opposing electrodes. The opposing inner surfaces of the pair of substrates have been subjected to an aligning treatment such that the liquid crystal placed in one of the two stable states moves under application of an electric field in a direction identical to one in which the liquid crystal placed in the other of the two stable states moves under the application of the electric field. The liquid crystal device has an effective optical modulation region and a peripheral region outside the effective optical modulation region, wherein the effective optical modulation region and the photosensitive member have been subjected to different aligning treatments. In the liquid crystal device thus constituted, a liquid crystal movement liable to cause yellowing or fluctuation in drive parameters otherwise is effectively compensated by a liquid crystal movement in the peripheral region.

    摘要： A liquid crystal device is constituted by a pair of oppositely disposed substrates having opposing inner surfaces and opposing electrodes thereon, and a chiral smectic liquid crystal disposed between the opposing electrodes. The liquid crystal device has an effective optical modulation region and a peripheral region outside the effective optical modulation region. In the device, liquid crystal molecules in the peripheral region have a pretilt angle which is larger than a pretilt angle of liquid crystal molecules in the effective optical modulation region. As a result, a local pressure irregularity or a cell thickness change caused by a liquid crystal molecular movement along an extension of the device is effectively suppressed.

    摘要： A liquid crystal device suitable as a display device is produced through a process wherein a chiral smectic liquid crystal is injected into a blank cell in a temperature where two higher temperature phases, such as isotropic phase and cholesteric phase or cholesteric phase and smectic A phase, of the liquid crystal are co-present. As a result, the liquid crystal injection is completed in a relatively short period to provide the liquid crystal device with a uniform alignment characteristic of the liquid crystal.

    摘要： A ferroelectric liquid crystal device is constituted by disposing a ferroelectric liquid crystal between a pair of substrates having thereon electrodes for voltage application and provided with uniaxial alignment axes, as by rubbing, so as to provide a high pretilt angle of at least 10 degrees. A problematic liquid crystal movement in such a high-pretilt angle ferroelectric liquid crystal device is suppressed by improving a smectic layer structure therein, inclusive of a symmetry of pretilt angles at the pair of substrate boundary surfaces. Such an improved smectic layer structure is accomplished by a realigning treatment after cooling to the chiral smectic phase or in the final stage of the cooling to the chiral smectic phase as by application of an AC electric field and/or by repetitive heating-cooling in the chiral smectic phase. The improved smectic layer structure is represented by, e.g., an X-ray diffraction peak having an increased peak area and/or a decreased half-value width.

    摘要： A liquid crystal device is constituted by a pair of oppositely disposed substrates each provided with a plurality of electrodes and a chiral smectic liquid crystal disposed so as to fill a prescribed gap between the substrates together with a plurality of spacers dispersed therein. The substrates includes a substrate having four sides at least one of which has a connecting portion to be connected with a drive circuit supplying a voltage to associated electrodes. The prescribed gap is decreased with an increasing distance from the connecting portion, whereby an uneven temperature distribution within the device resulting from heat generation in the vicinity of the connecting portion for the drive circuit can be alleviated or minimized to improve a display irregularity.
