Abstract
The ferroelectric liquid crystal (FLC) which has the advantage of a fast response under an electrical field has become one of the most promising candidates of the next generation liquid crystal display (LCD) as well as photonic devices. In the display area, sub‐millisecond switching is needed to enable field sequential color (FSC) display technology, which improves resolution and efficiency at least by three times when using sequentially coming RGB colors instead of color filters. The FLC allows electrical control of the response time in the range from several microseconds to several seconds. FLC devices also have a great potential in the sensing and detection area since a microsecond response is in high demand for real time sensors. Gratings, optical switches and phase modulators can also be fabricated with FLC, and applied in optical communications, imaging systems, etc.
