摘要:
A difluoride derivative represented by the general formula: R?1-(A1-Y1)¿m-A2-CF=CF-C=C-A?3-(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 R?1 and R2¿ represent each C¿1?-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.
