Abstract:
An optical film has a cellulose acylate film base material containing cellulose acylate and a plurality of sugar ester compounds having different ester substitution degrees in which an average ester substitution degree of the plurality of sugar ester compounds is from 60 to 94%, and an antistatic hardcoat layer formed from a coating composition containing at least an organic antistatic agent and a curable compound having a (meth)acryloyl group in a molecule of the curable compound.
