摘要

An optical film including at least one compound represented by formula (1) is disclosed. In the formula, Y11, Y12 and Y13 each independently represent methine or a nitrogen atom; R11, R12 and R13 each independently represent formula (A), (B) or (C) or a hydrogen atom, provided that at least two of R11, R12 and R13 each independently represent formula (A), (B) or (C). In the formulae, L12, L22, and L32 each represent a 5-membered heterocyclic group.;
