A liquid crystal optical element comprising:
(a) an oriented ferroelectric liquid-crystalline polymer layer which exhibits chiral smectic C phase, and
(b) 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.
液晶光学元件,包括
(a) 取向铁电液晶聚合物层,该层呈现手性共晶 C 相,以及
(b) 两个导电层,在它们之间支撑取向铁电液晶聚合物层,其中两个导电层中至少有一个是透明的。
这种液晶光学元件可以很容易地制成大面积的液晶光学元件,并可用作柔性显示屏。此外,它还具有出色的电场响应特性和高对比度。此外,液晶光学元件的生产和厚度控制也很容易进行。
