摘要： A ferroelectric liquid crystal device of a cell structure having a suppressed increase of cell thickness along a cell side is constituted by disposing a ferroelectric liquid crystal between a pair of electrode plates each sequentially provided with an electrode, an insulating film and an alignment film on a substrate. The alignment film is provided with a surface unevenness for suppressing a liquid crystal movement causing the increase in cell thickness. The surface unevenness is provided to the alignment film directly or to the insulating film below the alignment film, e.g., by wet forming the relevant film by using at least two solvents having different boiling points or dispersing fine particles within the relevant film, optionally followed by removal of the fine particles.

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.

摘要翻译：液晶装置由一对相对设置的基板，其上具有相对的内表面和相对的电极构成，并且在对置电极之间设置两个稳定状态的手性近晶液晶。一对基板的相对的内表面已经进行了对准处理，使得以两个稳定状态之一放置的液晶在施加电场的同时沿与其中放置的液晶的方向相同的方向移动两种稳定状态中的另一种在电场的应用下移动。液晶装置在有效光调制区域外具有有效的光调制区域和周边区域，其中有效光调制区域和感光构件已进行不同的取向处理。在这样构成的液晶装置中，通过周边区域的液晶运动可以有效地补偿易于引起黄变的液晶运动或驱动参数的波动。

摘要： A liquid crystal device is formed by applying an alignment film on at least one of a pair of substrates sandwiching a liquid crystal, preferably a chiral smectic liquid crystal. The alignment is formed by a dehydro-cyclization product of a polyamide acid which in turn is a reaction product of naphthalenetetracarboxylic acid or its derivative with a diamine or its derivative. The liquid crystal device provides a high contrast display, particularly by multiplexing drive, which is free from after-image because of quick responsiveness.
