Title:
LIQUID CRYSTAL COMPOUNDS HAVING SUBSTITUTED ALKYL GROUPS, LIQUID CRYSTAL COMPOSITION, AND LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/1996/041787
Kind Code:
A1
Abstract:
Liquid crystal compounds being excellent in compatibility with other liquid crystal materials and stability and having a low viscosity and a high isotropic phase transition temperature; a liquid crystal composition containing at least one of the compounds, and a liquid crystal display element using the composition. The abovbe compounds are represented by the following general formula (I): R-A1-Z1-A2-Z2-A3-Z3-A4-(-CH2-)-mX, wherein R is H or C1 to C10 alkyl (one or more methylene (-CH2-) groups of which may be replaced by -O- or the like); m is an integer of 1 to 10; X is F, Cl, Br, I or OH; A1, A2, A3 and A4 are each trans-1,4-cyclohexylene or the like; and Z1, Z2 and Z3 are each independently -(CH2)2- or a covalent bond, with at least two of Z1, Z2 and Z3 being covalent bonds.
