Method of producing a liquid crystal optical element.

摘要

A liquid crystal optical element comprising: (1) an oriented ferroelectric liquid-crystalline polymer layer which exhibits chiral smectic C phase, and (2) two electrically conducting layers which support the oriented ferroelectric liquid-crystalline polymer layer between them, where at least one of the two electrically conducting layers is transparent. The liquid crystal optical element can be easily made into one having a large area and can be used as flexible display screen. Further, it has excellent electric field response property and high contrast. Furthermore, the production of the liquid crystal optical element and the control of its thickness can be easily conducted.
