Liquid crystal electro-optical device and manufacturing method therefor

Claim 1

A liquid crystal device comprising: a pair of substrates; a chiral smectic liquid crystal layer interposed between said substrates; an electrode arrangement provided for defining a plurality of cell regions in said liquid crystal layer in array form and for applying an electric field to each region; and an orientation control surface formed on at least one inside surface of said substrates; wherein said liquid crystal layer comprises at least a material conforming to the formula; ##STR4## where R 1 is a hydrocarbon having at least 8 and not more than 10 carbon atoms, and R 2 is a hydrocarbon comprising at least two asymmetric carbon atoms wherein the difference in the number of carbon atoms between R 1 and R 2 is within 3 so that micro-domains are formed in said liquid crystal layer whereby each region consists of a plurality of micro-domains in each of which liquid crystal molecules are aligned in accordance with one direction which is different from the direction of liquid crystal molecules of adjacent micro-domains contiguous thereto.
