abstract |
The invention discloses a 3,4,5-trifluorobiphenyl liquid crystal compound with ethylene bridges, the general structural formula of which is shown in (1): Wherein R is a straight-chain alkane with 1 to 9 carbons. The 3,4,5-trifluorobiphenyl liquid crystal compound with ethylene bridge bonds has the advantages of wide liquid crystal phase region and large dielectric anisotropy, and is suitable for TN, STN, and TFT liquid crystal displays. |
