摘要：
A liquid crystal compound of the formula:
wherein
R 2 is preferably C 7 -14 alkyl; X1 is -COO- or -OCO; Y1 is
Y 2 is
; and Z is -N0 2 or -CN, shows a smectic phase, is large in positive dielectric anisotropy and can give a liquid crystal composition (5) suitable for use in a thermal address display device.
