摘要：
The present liquid crystal compounds are novel ester-type compounds showing a smectic liquid crystal phase and being capable of increasing a dielectric constant anisotropy, represented by the following general formula:
wherein R is an alkyl group; X 1 and X 2 are the same or different from each other and are group -COO- and -OOC-, and when X 1 is group -COO-,
Y 1 is group
and Y 2 is grou f
and when X I is group -OOC-, Y 1 is group
and Y2 is group
The present liquid composition contains the novel compound, and the present liquid crystal display device uses the liquid crystal composition for utilizing the characteristics of the novel compound. Particularly, the present liquid crystal display device is a thermally addressed display device.
