A conductive liquid-crystal material which even in a room temperature range has excellent conductivity at a low voltage, with the threshold voltage being about 5 V, and which changes in resistivity with applied voltage, undergoes an abrupt increase in current density at around a voltage of about 5 V, and has properties such as excellent charge mobility; and a liquid-crystal composition which is for use as the conductive liquid-crystal material. The conductive liquid-crystal material comprises a liquid-crystal composition comprising two or more ingredients having a smetic phase as a liquid-crystal phase, and is characterized in that one or more of the ingredients each is selected from distyryl derivatives represented by the following general formula (1) and the liquid-crystal composition comes into a solid state formed by a phase transition from the smetic phase. [Chemical formula 1] (1) (In the formula, R1 and R2 each represents linear or branched alkyl or alkoxy, provided that R1 and R2 may be the same or different.) |
