    摘要： A liquid crystal device, particularly a ferroelectric liquid crystal device, is constituted by disposing a liquid crystal disposed between a pair of rubbing-treated substrates. The uniaxial alignment control force exerted by rubbing is gradually weakened as the rubbing treatment is successively applied to a large number of substrates. This is compensated by varying a rubbing condition, such as a relative moving speed, a rotational speed, or a pressing depth against the substrate of a rubbing roller. Alternatively, such a change in uniaxial alignment control force with time may be utilized for compensating for a difference in uniaxial alignment control force attributable to a difference in stripe electrode extension relative to the rubbing direction.

    摘要： A liquid crystal device is formed by a pair of substrates each having thereon electrodes, and a liquid crystal disposed between the substrates so as to be movable along surfaces of the substrates. The liquid crystal is disposed over regions extending between the surfaces of the substrates including an effective optical modulation region, a first peripheral region outside the effective optical modulation region and a second peripheral region formed along a part or an entirety of outer periphery of the first peripheral region. The liquid crystal is disposed to have a higher liquid crystal molecular pretilt angle in the first peripheral region than in the effective optical modulation region. The liquid crystal is disposed in a random alignment state free from uniaxial alignment characteristic or in a layer structure in the second peripheral region. As a result, the liquid crystal molecular movement along the extension of substrates is suppressed in the effective optical modulation region and in the second peripheral region and relatively allowed in the first peripheral region, so that the impurities in the liquid crystal are confined in the second peripheral region while avoiding the liquid crystal thickness irregularity.

    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 ferroelectric liquid crystal device is constituted by a pair of substrates each having thereon a group of display electrodes, and a ferroelectric liquid crystal disposed between the substrates. Liquid crystal movement causing yellowing or local increase in liquid crystal layer thickness is minimized in the device by forming a substantial in liquid crystal layer thickness between a pixel part and a non-pixel part and/or by forming a groove having minute convexities with a maximum diameter of at least 0.1 .mu.m at non-pixel parts on a substrate so that the groove extends in a direction forming an angle of 45-135 degrees with a normal to smectic layers of the liquid crystal.
