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 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.
