摘要
The invention provides a liquid crystal compound having general physical properties necessary for a compound, stability to heat, light or the like, a wide temperature range of a liquid crystal phase, a high clearing point, an excellent compatibility with other liquid crystal compounds, a large refractive index anisotropy and a large dielectric anisotropy. The invention provides a liquid crystal composition that includes the liquid crystal compound and a liquid crystal display device that contains the liquid crystal composition. The compound provided is represented by formula (1): wherein, for example, R 1 is alkyl having 1 to 20 carbons; at least one of the ring A 1 to the ring A 6 is pyrimidine-2,5-diyl or pyridine-2,5-diyl and the others are 1,4-cyclohexylene or 1,4-phenylene; Z 1 to Z 6 are a single bond; L 1 to L 4 is hydrogen or halogen; X 1 is hydrogen, halogen, -C‰¡N or alkyl having 1 to 10 carbons; and 1, m, n, o, p and q are 0 or 1 and 1+m+n+o+p+q is 3.
