— We have developed novel liquid‐crystal (LC) materials with a difluoromethyleneoxy CF 2 O) moiety as the linkage group in order to satisfy the various requirements of active‐matrix liquid‐crystal displays (AMLCDs). We measured the physical properties of the CF 2 O LC materials. The novel CF 2 O LC materials have excellent physical properties, that is, high dielectric anisotropy, low viscosity, a broad nematic range, high reliability, etc . It was revealed that several advantages can be obtained by the introduction of CF 2 O moiety into the LC molecules. The mixture containing CF 2 O LC materials for various applications indicated a decrease in rotational viscosity of about 15–25% compared with that for conventional LC mixtures. Also, these novel mixtures with CF 2 O LCM demonstrated a higher voltage‐holding ratio (VHR). It was confirmed that mixtures containing CF 2 O LC materials have suitable characteristics for various applications, for example, low‐driving‐voltage note‐book PCs, quick response monitors, and transflective applications.
