An aromatic compound represented by the following formula (1).
[In the formula, ring A and ring B each represent a benzene ring, an aromatic fused ring composed of 2-4 rings, a heteroaromatic ring or a heterocyclic aromatic fused ring composed of 2-4 rings, R1a represents a group -CHR2a-CHR2bR2c, and R1b, R1c and R1d each represent hydrogen, aryl or a group -CHR2d-CHR2eR2f. This is with the proviso that at least 2 of R1b, R1c and R1d are not hydrogen. R2a, R2b and R2c each represent hydrogen, alkyl, aryl or a substituted silyl group, and R2a and R2b may be bonded together to form a ring. R2d, R2e and R2f each represent hydrogen, alkyl, aryl or a substituted silyl group, and R2d and R2e may be bonded together to form a ring.]
