摘要：
A compound of the formula (1), and a liquid crystal composition comprising the same:
wherein R and R ' are alkyl groups having 1 to 10 carbon atoms, cyano groups, halogen atoms; rings A 1 , A 2 , A 3 and A 4 are benzene, cycloalkane having 3 to 8 carbon atoms; at least one of Z 1 , Z 2 and Z 3 is an alkenylene group of the formula Q:
wherein P 1 and P 2 are hydrogen atoms or alkyl groups having 1 to 10 carbon atoms, provided that at least one of P 1 and P 2 is alkyl group having 1 to 10 carbon atoms, q and r are 0 to 2 and the sum of q + r is 2 or less; and the other of Z 1 , Z 2 and Z 3 are -CH 2 CH 2 -, m and n are 0 or 1. The liquid crystal compound of the invention has broader temperature range of a liquid crystal phase, excellent compatibility with other liquid crystal compounds, high stability and large elastic coefficient ratio K 33 /K 11 .
