液晶化合物、液晶組成物および液晶表示素子
Document Type and Number:
Japanese Patent JP5880832
Kind Code:
B2
Abstract:
To provide a novel liquid crystal compound having general physical properties necessary for the compound, namely, stability to heat, light and so forth, a wide temperature range of a liquid crystal phase, a high clearing point, a good compatibility with other compounds, a large refractive index anisotropy, a large dielectric anisotropy and a small viscosity.
The liquid crystal compound is provided as compound (1):
wherein, for example, R 1 is alkyl having 1 to 20 carbons; ring A 1 and ring B 1 are 1,4-cyclohexylene or 1, 4-phenylene; Z 1 and Z 2 are a single bond, -CH 2 CH 2 -, -CH=CH- or -C‰¡C-; L 1 is fluorine; L 2 , Y 1 and Y 2 are hydrogen, fluorine or chlorine; and X 1 is halogen, -C=N or alkyl having 1 to 10 carbons, and in the alkyl, arbitrary -CH 2 - may be replaced by -O- or -S-, and m is 1 and n is 0.
