Disclosed is a visible light-transmissive liquid-crystalline compound having good hole and electron-transport characteristics and useful as an organic semiconductor material. The compound is represented by a formula (1):
wherein R independently represents hydrogen, or alkyl having from 1 to 24 carbon atoms, and any —CH
2
— in the alkyl may be replaced by —O—, —S—, —CO— or —SiH
2
—, any —(CH
2
)
2
— may be replaced by —CH≡CH— or —C═C—, and any hydrogen may be replaced by halogen; Ar represents naphthylene, anthrylene, phenanthrylene, or phenylene; and every hydrogen in phenylene is replaced by halogen, and any hydrogen in naphthylene, anthrylene and phenanthrylene may be replaced by halogen.
