摘要

对表面稳定铁电液晶器件中C

和C

两种排列态的自由能密度与表面取向情况的依赖关系做了理论模拟

得出采用较小预倾角的取向剂制备铁电液晶器件

可以消除器件中的Zigzag缺陷的结论。实验中采用预倾角为1.8的取向剂RN-1199

得到了没有Zigzag缺陷的均匀排列器件。

Abstract

Free energy that includes bulk elastic and surface parts has been theoretically simulated depending on surface topography. The critical conditions of the state transition from C

to C

have been determined. Based on this theory

the defect-free FLCDs with uniform alignment was successfully fabricated by means of using alignment layer RN-1199 which can provides a low pretilt angle of 1.8.
