    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 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 rubbing treating apparatus, comprising: a stage for mounting thereon an electrode substrate provided with an alignment control film, a rubbing cloth for effecting rubbing treatment by rubbing it against the alignment control film, a rubbing mask mounted on the stage so as to cover at least a part of the electrode substrate, and a holding means for causing at least the rubbing mask to closely contact the stage, wherein the rubbing mask is caused to closely contact the stage at the time of rubbing treatment. The rubbing mask is effective in imparting an alignment control power to the surface of the alignment control film, effecting uniform rubbing treatment with respect to a desired region and preventing an occurrence of alignment defects and a deterioration of the rubbing cloth.

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.
