Abstract:
Provided is a liquid crystal compound represented by formula I, the compound having a positive dielectric anisotropy, a great elastic constant and a good solubility. Further provided is a liquid crystal composition comprising the liquid crystal compound represented by formula I, the liquid crystal composition having a good stability against light and heat, a lower viscosity, a wider refractive index that may be achieved by the adjustment of the monomer ratio, and a higher clearing point (a very wide service temperature range), and in particular, the liquid crystal composition has a higher light transmittance, thus allowing a display device to have a higher brightness or an energy saving effect.

Claim (Index 8):
The liquid crystal composition according to  claim 7 , wherein said one or more compounds represented by formula III are compounds of formulas III1 to III22 wherein X 1  and X 2  each independently represent H or F; wherein each R 4  independently represents an alkyl group having a carbon atom number of 1-10, a fluoro-substituted alkyl group having a carbon atom number of 1-10, an alkoxy group having a carbon atom number of 1-10, a fluoro-substituted alkoxy group having a carbon atom number of 1-10, an alkenyl group having a carbon atom number of 2-10, a fluoro-substituted alkenyl group having a carbon atom number of 2-10, an alkenoxy group having a carbon atom number of 3-8 or a fluoro-substituted alkenoxy group having a carbon atom number of 3-8, and any CH 2  in group of R 4  may be substituted with cyclopentyl, cyclobutyl or cyclopropyl; (F) represents H or F; and Y 2  represents F, a fluoro-substituted alkyl group having a carbon atom number of 1-5, a fluoro-substituted alkoxy group having a carbon atom number of 1-5, or an alkenyl group having a carbon atom number of 2-5.
