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 formed by applying an alignment film comprising a fluorine-containing polyimide having a fluorine-containing substituent in its moiety originated from a diamine on at least one of a pair of substrates sandwiching a chiral smectic liquid crystal. Preferably, the respective substrates are provided with such fluorine-containing polyimide alignment films which have been rubbed in directions which are substantially parallel with each other and identical to each other or which intersect each other at a small counter-clockwise intersection angle. The liquid crystal device thus formed shows a high contrast display, particularly by multiplexing drive, free from after-image because of quick responsiveness.
