WIPO Patent Application WO/1994/005613

A1

A difluoride derivative represented by the general formula: R1-(A1-Y1)m-A2-CF=CF-C=C-A3-(Y2-A4)n-R2, wherein A1 through A4 represent each trans-1,4-cyclohexylene, 1,4-cyclohexenylene or 1,4-phenylene; m and n represent each 0 or 1; and R1 and R2 represent each C1-C10 alkyl, halogen or cyano. The compound is lowly viscous and light-stable, and hence can provide a liquid crystal composition having high response speed.
