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.

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.
