Abstract

Striped electrodes are formed on upper and lower substrates respectively, and a plurality of partition members are formed in a striped fashion so that a plurality of parallel sealed linear interstices R, each having a rectangular section, are formed between the substrates. A upper-side rubbing direction crosses a lower-side rubbing direction at a predetermined angle, and the direction of extension of each of the partition members is caused to fall within the above cross angle. An antiferroelectric liquid crystal is sealed in the linear interstices, and the liquid crystal panel is cooled while proceeding from one end of the linear interstices to the other end thereof. The layer normal direction of liquid crystal molecular layer becoming irregular between the upper and lower substrates is prevented by the employment of the cross rubbing method to thereby avoid the occurrence of defects in the liquid crystal. Further, the occurrence of zigzag defects is prevented by controlling the infiltration of the antiferroelectric liquid crystal and also controlling the cooling.
