Swallow-tailed compound and ferrielectric liquid crystal composition containing the same |
摘要 |
<p>A swallow-tailed compound of the following general formula (1), <CHEM> wherein m is an integer of 4 to 10, n is an integer of 2 to 6, p is 0 or 1 and each of X and Y is independently a hydrogen or fluorine atom; and a ferrielectric liquid crystal composition consisting essentially of the swallow-tailed compound of the general formula (1) and a ferrielectric liquid crystal compound of the following general formula (2), <CHEM> wherein R is a linear alkyl group having 6 to 12 carbon atoms, Z is a hydrogen or fluorine atom, r is an integer of 2 to 4 and s is an integer of 2 to 4. The ferrielectric liquid crystal composition has a ferrielectric phase in a broad temperature range and attains a fast response and a large tilt angle in a broad temperature range so that a ferrielectric liquid crystal display device having high display qualities can be provided.</p> |
