    摘要: Provided is a liquid crystal composition, comprising: 1-30% of one or more compounds of general formula I; 1-50% of one or more compounds of general formula II; 1-20% of one or more compounds of general formula III; 20-70% of one or more compounds of general formula IV; and 1-30% of one or more compounds of general formula V. The liquid crystal composition has properties such as a large maximum absolute transmittance, a high voltage holding ratio, better anti-UV properties, and high temperature reliability, and has a suitable optical anisotropy, a suitable dielectric anisotropy, and a relatively high clearing point, and is environmentally friendly. The liquid crystal composition is suitable for use in a liquid crystal display device, especially a transmissive liquid crystal display element, enabling the liquid crystal display device to have properties such as a high maximum absolute transmittance, a high voltage holding ratio, good anti-UV properties and high temperature reliability, and to be energy-saving and environmentally-friendly.
