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.

摘要： A liquid crystal composition includes at least one compound of general formula I, at least one compound of general formula II and at least one compound of general formula III. The liquid crystal composition has a higher optical anisotropy, the relatively large elastic constants K11 and K33 while maintaining a relatively high clearing point, an appropriate dielectric anisotropy and a better low-temperature intersolubility. A liquid crystal display device which includes the liquid crystal composition has advantages of a fast response, a high contrast and a wide temperature range, thereby having a good display effect and a large range of applicability.
