From discovery of a ferroelectric nematic phase to present developments: Scientific deepening and applications challenge

Abstract

The nematic liquid crystal (NLC) has truly three-dimensional fluidity because of nematogens exhibit only orientational but no positional order. The unique electro-optical effect in NLCs has led the portable computing revolution of the 20th century in the LC display technologies. In sharp contrast, a new class matter state, a ferroelectric nematic liquid crystal (NFLC), in which the local nematic director is non-degenerate, is of great fundamental interest, and its exceptional large polarization behavior as well as its high fluidity offers state-of-the-art applications challenge. In this presentation, the global trends, world-historical event including our recent achievements, on NFLCs will be introduced.
