ABSTRACT:
Provided are a liquid crystal compound represented by formula 1, a liquid crystal composition including the same, and a liquid crystal display including the liquid crystal composition:wherein X1, X2, R1, R2, L andare the same as described in specification. High optical anisotropy and negative dielectric anisotropy can be achieved by the use of the liquid crystal composition including the liquid crystal compound.
