ABSTRACT:
A light deflection element has a pair of transparent substrates2, 3; a chiral smectic C phase liquid crystal5with a homeotropic alignment filled between the pair of transparent substrates2, 3; and at least an electric field applying device6for activating an electric field in the liquid crystal5. Because a chiral smectic C phase liquid crystal is used, the problems of the conventional light deflection element, such as high cost, light loss, large size, and optical noise etc. due to its complicated structure, can be greatly improved. The conventional low response time due to the smectic A phase or the nematic liquid crystal is improved, thereby the high-speed response is possible.
