Liquid crystal composition for optical compensation bending mode liquid crystal display

Abstract

The invention discloses a liquid crystal composition for an optical compensation bending mode liquid crystal display, which overcomes the defects of non-superposed penetration curves of conventional skills and long time required for switching states. The liquid crystal composition contains a nematic liquid crystal material and a palm-opposition dextral activated substance, wherein the palm-opposition dextral activated substance is shown in a formula (1).

Description

technical field The present invention relates to liquid crystal compositions, and in particular to liquid crystal compositions for use in optically compensated bend mode liquid crystal displays. Background technique In recent years, the rapid development of imaging technology has made liquid crystal displays (Liquid Crystal Displays; LCDs) which are thin in size, light in weight and have low electromagnetic radiation gradually become mainstream products of displays. Liquid crystals can generally be divided into three types according to different condensation structures: nematic liquid crystal, smectic liquid crystal and cholesteric liquid crystal. Among them, the bent nematic liquid crystal mode (Bend Nematic Mode) was first discovered by the R&D team of P.J.Bos in 1984 and its structural concept was proposed. If the alignment rubbing (Rubbing) direction of the horizontally aligned liquid crystal (Homogeneous cell) substrate is used as the benchmark (anti-parallel rubbing t...
