ABSTRACT:
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 relavant film, optionally followed by removal of the fine particles.
