Perfluoropolymer Surface for Shock-Free Homeotropic Alignment of Smectic Liquid Crystals

摘要

In order to use liquid crystals (LCs) in practical applications such as liquid crystal displays (LCDs) and photonic optical devices, a uniform director orientation of LC molecules is essential. In particular, vertical alignment (VA) of nematic LC molecules has been studied and applied in VA-mode LCDs, owing to their superior properties such as wide viewing angle and high contrast ratio compared to the conventional twisted-nematic display.
