Ferroelectric smectic liquid crystal device |
摘要 |
A ferroelectric smectic liquid crystal device having an improved impact resistance and an improved contrast is provided by using a pair of substrates provided with uniaxial alignment axes which are parallel and identical in direction with each other. A ferroelectric smectic liquid crystal is disposed between the pair of substrates so as to assume a higher-temperature alignment state and a lower-temperature alignment state on temperature decrease in its ferroelectric smectic phase placed in a bistable alignment state. The ferroelectric smectic liquid crystal is further placed in the lower-temperature alignment state which is characterized by having an inclination of forming a connected pair of a lightning defect and a hair pin defect coming after the lightning defect.
