Development of Liquid Crystal Compounds with Large Negative Dielectric Anisotropy

Abstract

To solve some inherent problems of LC compound with negative Δε (N-LC), we have designed and synthesized novel N-LChaving polycyclic aromatic hydrocarbons. These compounds have quite larger values of negative Δε in comparison with conventional N-LCs. Mixtures including these compounds give lower viscosity and the response time of displays which were used is shorter than that of conventional N-LC.
