Document Type and Number:
Japanese Patent JP5011598
Kind Code:
B1
Abstract:
A nematic phase liquid crystal compound with negative dielectric constant has a structure represented by wherein R1 represents a hydrogen atom or linear alkyl having 1 to 8 carbon atoms or linear alkenyl having 1-8 carbon atoms, or an alkoxy or alykenoxy formed by substituting one or nonadjacent two CH2 in the linear alkyl or alkenyl with oxygen atom, wherein 0 to 4 hydrogen atoms of R1 group can be substituted with fluorine; R2 represents a hydrogen atom or linear alkyl having 1 to 8 carbon atoms, or R2 represents a linear fluoroalkyl having 1 to 8 carbon atoms, in which group 1 to 4 hydrogens can be substituted with fluorine atoms; A represents a benzene ring or 1,4-cyclohexane ring, if A is a benzene ring 0 to 4 hydrogen atoms on the benzene ring may be substituted with fluorine; n=1 to 2, and m=0 to 2.
