摘要：
A novel phenylpyridine derivative which exhibits a positive dielectric anisotropy and is useful as a component of liquid crystal materials and also has a broad temperature range of liquid crystal phases, a high clearing point and a superior compatibility with other liquid crystal compounds or liquid crystal compositions, and a composition containing the derivative are provided. The phenylpyridine derivative is expressed by the formula ##STR1## wherein R represents an alkyl group of 1 to 10 carbon atoms, X represents H or F; Y represents F, --CN or an alkyl group or an alkoxy group of 1 to 10 carbon atoms; and m represents 0 or 1.
