Perfluoropolymer as planar alignment layer for liquid crystal mixtures

Abstract

We report a perfluoropolymer (CYTOP) provides planar alignment to liquid crystal mixtures (e.g., ZLI-2293) that are used in display. We found that the anchoring energy of ZLI-2293 on CYTOP is almost eighteen times less and the pretilt angle is slightly larger than on AL-1254. It is expected that the low surface anchoring and high transmission in CYTOP cell will make CYTOP a suitable aligning agent for LC displays as well as many other LC devices. © 2011 The Japan Society of Applied Physics.
