摘要:
A liquid crystal cell is constituted by a pair of substrates respectively provided with scanning electrodes or data electrodes and uniaxial alignment axes which are substantially parallel with each other and substantially in the same direction, and a ferroelectric liquid crystal disposed between the substrates. At least one of the substrates is provided with ridges having a height at least one third of the spacing between the substrates or stripe transparent electrodes having thereon a stripe conductor film extending in the longitudinal direction of an associated one of the stripe transparent electrodes.
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 ferroelectric liquid crystal device is constituted by a pair of substrates each having thereon a group of display electrodes, and a ferroelectric liquid crystal disposed between the substrates. Liquid crystal movement causing yellowing or local increase in liquid crystal layer thickness is minimized in the device by forming a substantial in liquid crystal layer thickness between a pixel part and a non-pixel part and/or by forming a groove having minute convexities with a maximum diameter of at least 0.1 .mu.m at non-pixel parts on a substrate so that the groove extends in a direction forming an angle of 45-135 degrees with a normal to smectic layers of the liquid crystal.
