Claim:
A terphenylene derivative represented by the following formula (1): wherein the substituents R 1 to R 14 are the same or different and each represents a hydrogen atom, a fluorine atom, a chlorine atom, an aryl group having 4 to 30 carbon atoms, an alkenyl group having 2 to 30 carbon atoms, an alkyl group having 1 to 20 carbon atoms or a halogenated alkyl group having 1 to 20 carbon atoms, or a diarylamino group having 8 to 30 carbon atoms; the substituents R 3 and R 4 are combined to form an unsaturated ring and the substituents R 10 and R 11 are combined to form an unsaturated ring, or only the substituents R 3 and R 4 are combined to form an unsaturated ring, or only the substituents R 10 and R 11 are combined to form an unsaturated ring; and l, m, and n each represents an integer of 0 or 1; when 1=0, m=0, and n=0, when 1=1, m=0, and n=0, or when 1=0, m=1, and n=0, at least one of the substituents R 1 to R 14 is not a hydrogen atom.
