A naphthalene derivative represented by the following formula (1) is provided. In the formula (1), Ar1 to Ar6 each represent a substituted or unsubstituted aromatic hydrocarbon cyclic group having 6 to 18 carbon atoms forming a ring. The substituted or unsubstituted aromatic hydrocarbon cyclic group has none of anthracene skeleton, pyrene skeleton, aceanthrylene skeleton and naphthacene skeleton. R1 to R3 each represent an alkyl group, a cycloalkyl group, an alkoxy group, a cyano group, a silyl group or a halogen atom. R1 to R3 each may be bonded in any position of a main-chain naphthalene skeleton or a main-chain benzene skeleton. a and b each represent an integer in a range of 0 to 4. l, m, n and p each represent 0 or 1.
