(57) [Summary] [Structure] General formula [R 1 is an alkyl group having 1 to 18 carbon atoms, A is NAP at the 2-position and a pyridine ring, a pyrimidine ring or a 2,3-difluoro-1,4-phenylene group bonded to R 1 at the 5-position, etc. , NAP is a 2,6-naphthylene group, C * is an asymmetric carbon atom, n is an integer from 0 to 9, and R 2 is from 2 to 1 carbon atoms. 0 alkyl group]. [Effect] By using this liquid crystal compound as a component of a liquid crystal composition exhibiting a chiral smectic C phase, it is possible to obtain a liquid crystal composition having a good orientation and no zigzag defects, and a liquid crystal display device having a high contrast ratio. Obtainable. |
