A liquid-crystalline styryl derivative characterized by being represented by the following general formula (1). (1) In the formula (1), R1 and R2 are the same or different and each represents linear or branched alkyl, alkoxy, cyano, nitro, fluorine,-C(O)O(CH2)m-CH3,-C(O)-(CH2)m-CH3, or a group represented by the following general formula (2). (2) In the formula (2), R3 represents hydrogen or methyl; B represents-(CH2)m-,-(CH2)m-O-,-CO-O-(CH2)m-,-CO-O-(CH2)m-O-,-C6H4-CH2-O-, or-CO-; and m is an integer of 1-18. Preferably, R1 and R2 in the general formula (1) are the same or different and each is branched alkyl or alkoxy represented by CH3-(CH2)x-CH(CH3)-(CH2 )y-CH2-or CH3-(CH2)x-CH(CH3)-(CH2 )y-CH2-O-(wherein x is an integer of 0-7 and y is an integer of 0-7). This styryl derivative is suitable for use as an organic semiconductor material.
