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： An aligning method of a chiral smectic liquid crystal showing a phase transition series of isotropic phase, smectic phase, and chiral smectic phase in this order on temperature decrease is provided. In the aligning method, the chiral smectic liquid crystal is disposed between a pair of electrode plates at least one of which is provided with an alignment control layer, preferably one having been subjected to a uniaxial aligning treatment (e.g., rubbing), and then is subjected to a treatment including a cycle of heating and cooling in temperatures ranging between a lower limit temperature showing chiral smectic phase and an upper limit temperature showing isotropic phase and smectic phase in mixture. The upper limit temperature may preferably be below an isotropic-smectic phase transition temperature by at most 3.degree. C., particularly at most 1.degree. C. The aligning method is effective in improving an alignment characteristic of liquid crystal molecules to provide a uniform alignment state free from an aligning defect.
