Abstract
ABSTRACT Stable ferroelectric liquid crystal (FLC) elements have been realised by optically stabilised alignment film and thermally stabilised alignment film. The two methods of fabricated FLC elements have been explored for different aspects, namely alignment quality, electro-optical response and their possibility for complicate aligning patterns such as grating and Pancharatnam–Berry lens. They are compared based on different requirements of applications. With these two approaches, we are able to produce various types of FLC photonic and display devices with good photostability.
