    摘要: A novel liquid crystal composition comprising three components: at least one difluoro-oxymethane derivative, at least one trifluorophenyl derivative and a monofluorophenyl dervivative. The composition exhibits a high voltage holding ratio at high temperatures, sufficiently low threshold voltage and large optical anisotropy, while satisfying general characteristics required for the AM-LCD display mode.
