Document Type and Number:

Japanese Patent JP4320824

Kind Code:

B2

Abstract:

The present application relates to a liquid crystal composition having a µ of not less than 0 comprising at least two components, characterized by containing at least one liquid crystalline compound represented by the general formula (1): where, R 1 represents hydrogen, fluorine, an alkyl group having 1 to 15 carbon atoms or an alkenyl group having 2 to 15 carbon atoms; each of rings A 1 , A 2 and A 3 independently represents trans -1,4-cyclohexylene group, 1,4-cyclohexenylene group, trans -1,4-silacyclohexylene group, 1,4-phenylene group, 2,3-difluoro-1,4-phenylene group, 2-fluoro-1,4-phenylene group, 3-fluoro-1,4-phenylene group, pyrimidine-2,5-diyl group, pyridine-2,5-diyl group, 1,3-dioxane-2,5-diyl group, tetrahydropyrane-2,5-diyl group, 1,3-dithiane-2,5-diyl group or tetrahydrothiopyrane-2,5-diyl group; X 1 represents hydrogen or fluorine; Y 1 represents hydrogen or an alkyl group having 1 to 15 carbon atoms, in which each of optional nonadjacent methylene groups (-CH 2 -) may be substituted by oxygen; 1 represents an integer from 0 to 10; in which each of optional nonadjacent methylene groups in (-CH 2 -) 1 may be substituted by oxygen; and each of m and n independently represents 0 or 1.
