摘要

This optical film (15) comprises a curing layer (13) on at least one surface of a transparent base (film base (12)). The transparent base is a cellulose film having a thickness of 5 μm or more but less than 35 μm. The curing layer (13) contains at least one active energy ray-curable resin (A) having a non-aromatic ring structure and at least one compound (B) having a ring structure and a first acid dissociation constant (pKa1) of from 1.0 to 7.0 (inclusive).
