One aspect of the present invention pertains to a production method for a cellulose acylate film, wherein: a web is formed by flow casting a polymerizable compound on a support, said compound containing a cellulose acylate, a polymerizable compound, and a thermal polymerization initiator having a 10-hour half-life temperature at 60 to 150°C; the polymerizable compound contained in the web that is formed is polymerized; and thermal polymerization is performed by means of a heat treatment process that involves heating the formed web at 120°C or above. Other aspects of the present invention pertain to a cellulose acylate film, a polarizing plate, and an image display device. |
