Twisted liquid crystal pi cell stabilized by polymer-sustained alignment
Tien-Jung Chen, Yuan-Hsin Cheng, and Sheng-Ming Wu
A uniform pi-twist liquid crystal (LC) alignment was stabilized in a pi cell by photopolymerization of a minute amount of monomers without using any chiral material. Controlling UV exposure time can vary the LC pretilt angle to achieve a stabilized pi-twist state. This type of pi-twisted LC cell mad ... [Appl. Phys.
