Abstract:
Disclosed is a liquid crystal compound with negative dielectric anisotropy, having a general formula as Formula 1. In Formula 1, each of L1, L2, L3, and L4, being same or different, is hydrogen, halogen, or cyano group. Each of R1 and R2, being same or different, is hydrogen, halogen, C1-12 alkyl group, C1-12 alkoxy group, C1-12 haloalkyl group, C2-12 alkenyl group, C2-12 ether group, or C2-12 alkynyl group. Each of A1 and A2, being same or different, is benzene, cyclohexane, or cyclohexene.Z1 is —CF2O—, or —OCF2—, and Z2 is —CF2O—, or —OCF2—.
