ABSTRACT:
A liquid crystal device, includes: (a) a first substrate and a second substrate, (b) an elongated first electrode disposed on the first substrate and an elongated second electrode disposed on the second substrate so as to intersect the first electrode and form a pixel at the intersection of the first and second electrodes, (c) a linear projection disposed along the length of at least one of the first and second electrodes, and (d) a chiral smectic liquid crystal disposed between the first and second substrates in a thickness small enough to suppress the formation of a helical structure inherent to the chiral smectic liquid crystal in its bulk state. The chiral smectic liquid crystal forms a domain in such an alignment state that the liquid crystal has an inclination of forming or actually forms a pair of a hairpin defect and a lightning defect, the hairpin defect being disposed closer to the linear projection than the lightning defect.
