SUMMARY OF THE INVENTION An object of the present invention is to provide a cellulose ester film excellent in planarity and haze, to reduce coating unevenness when the hard coat layer is applied on the cellulose ester film, to increase uniformity, and to prevent light leakage and front contrast. It is providing the optical film excellent in visibility, such as these, and providing the polarizing plate and liquid crystal display device which were excellent in the visibility which has the said optical film. The optical film of this invention has a hard-coat layer at least on a cellulose ester film, and the said cellulose ester film esterified the compound which combined 1 or 12 or more of at least 1 sort (s) of a furanose structure or a pyranose structure. An esterification compound is contained, and the esterification compound is an esterification compound in which a part of OH group remains. |
