(57) [Summary] [Structure] General formula R 1 -AC≡C-NAP-OR 2 [R 1 is an alkyl group having 1 to 18 carbon atoms, A is -C≡C- at the 2-position and 5 A pyridine ring bonded to R 1 at the -position or a 2,3-difluoro-1,4-phenylene group, NAP represents a 2,6-naphthylene group, and R 2 represents an alkyl group or an alkenyl group having 1 to 18 carbon atoms]. [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. |
