Abstract:
The present invention discloses a liquid crystal composition comprising: 15-35% by weight of a compound of general formula I; 3-20% by weight of a compound of general formula II; 5-30% by weight of a compound of general formula III; 1-20% by weight of a compound of general formula IV; 10-35% by weight of a compound of general formula V-1 and/or a compound of general formula V-2; and 1-25% by weight of a compound of general formula VI. The liquid crystal composition provided by the present invention has the characteristics of an appropriate optical anisotropy, an appropriate dielectric anisotropy, a higher clearing point, a better voltage holding ratio, and a good UV-resistant stability, etc., and can be applied to a liquid crystal display.
