Beschreibung
Zusammenfassung:	The invention discloses a cholesteric liquid crystal composition. The liquid crystal composition comprises one or more compounds as shown in a formula I, one or more compounds as shown in a formula II, one or more compounds as shown in a formula III and one or more compounds as shown in a formula IV. The liquid crystal composition has large optical anisotropy (delta n), high charge retention rate (VHR), small viscosity and large dielectric anisotropy, and can be used in electronic books and other optical devices. # imgabs0 # 本发明公开了一种胆甾相液晶组合物，该液晶组合物包含一种或多种式Ⅰ所示化合物、一种或多种式Ⅱ所示化合物、一种或多种Ⅲ所示化合物以及一种或多种式Ⅳ所示化合物。该液晶组合物具有较大的光学各向异性(Δn)、高的电荷保持率(VHR)、粘度小且介电各向异性大，可以用于电子书等光学器件中。#imgabs0#
