Provided is a liquid crystalline organic semiconductor material which can be practically applicable as an organic semiconductor. A liquid crystalline organic semiconductor material which is a liquid crystalline composition having a smectic phase as a liquid crystalline phase, characterized in that the material has a distyryl benzene structure represented by the following general formula (1) and exhibits a solid state formed by the phase transition from a smectic phase when the material is heated to a temperature within the range where the material takes a smectic liquid crystalline state and subsequently is cooled. [Chemical formula 1] (1) wherein R1 and R2 may be the same as or different from each other and represent any of an alkyl group, an alkoxy group and a group represented by the following general formula (2): (2) where R3 represents a hydrogen atom or a methyl group, and B represents-(CH2)m-,-(CH 2)m-O-,-CO-O-(CH2)m,-CO-O-(CH2)m-O-,-C6H4-CH 2-O-, or-CO-).
