Kind Code:
B2
Abstract:
There can be provided a liquid crystalline compound expressed by the general formula (1): wherein R represents a hydrogen atom, a cyano group, a halogen atom, a C1 to C20 alkyl group or a halogenated alkyl group, B1, B2, B3 and B4 are independently a covalent bond or a C1 to C4 alkylene group, n1, n2, n3, n4, m1, m2 and m3 are independently 0 or 1, rings A1, A2, A3 and A4 are independently a benzene ring in which one to four hydrogen atoms may be replaced by halogen atoms, bicycloÄ1.1.1Üpentane ring, bicycloÄ2.1.1Ühexane ring, bicycloÄ2.2.1Üheptane ring, bicycloÄ2.2.2Üoctane ring, naphthalene ring, 1,2,3,4-tetrahydronaphthalene ring, perhydronaphthalene ring, fluorene ring, phenanthrene ring, 9,10-dihydrophenanthrene ring, indan ring, indene ring, pyridine ring, pyrimidine ring, C4 to C20 cycloalkane ring or cycloalkene ring, G represents any one of groups represented by the formulae (G1) to (G3): wherein Q1, Q2, Q3 and Q4 are independently a covalent bond, an oxygen atom, a sulfur atom, -CH2-, -CH2CH2-, -CH=CH-, -CO-, -CF=CF- or -CF2-, the number of covalent bonds is 2 or less, Q1 and Q4 are preferential, the oxygen atom and the sulfur atom are not adjacent to each other, Q5 and Q6 are independently =CH-, =CF- or =CCl-, Y1 and Y2 are independently a hydrogen atom, a halogen atom, a cyano group, a nitro group, an amino group, or a C1 to C20 alkyl group or halogenated alkyl group, as well as a liquid crystal composition comprising the same, and a liquid crystal display device fabricated by using the same, and these are used in various liquid crystal display devices including TFT type.
