The present invention provides a conductive liquid-crystal material having features including that, for example, excellent conductivity is exhibited at a low threshold voltage of about 5 V even in a room temperature range, the value of resistance varies with an applied voltage, the current density rises sharply at a voltage of about 5 V, and an excellent charge mobility is exhibited, as well as a process for producing the conductive liquid-crystal material, a liquid-crystal composition which is used for the conductive liquid-crystal material, a liquid-crystal semiconductor element, and an information recording medium.The conductive liquid-crystal material is characterized by being a liquid-crystal composition composed of at least two components having a smectic phase as a liquid-crystal phase, wherein at least one component 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 smectic phase. (In the formula, R1 and R2 independently represent a linear or branched alkyl group or an alkoxyl group, and R1 and R2 may be the same group or different groups.)
