There is provided a cellulose acylate film, containing a hindered amin-based compound, wherein the hindered amine-based compound is contained in an amount of 0.001% by mass to 5% by mass based on cellulose acylate, a minimum value of Knoop hardness is 170 N/mmto 220 N/mm, and the Knoop hardness is measured several times by a Knoop indenter, the Knoop indenter is rotated by a given angle in each measurement, and a rotation axis of the Knoop indenter is orthogonal to an upper surface of the cellulose acylate film.

Cellulose acylate film, protective film for polarizing plate, polarizing plate, and liquid crystal display device

A free standing film having excellent mechanical strength and flexibility as well as sufficient area is provided. The organic-inorganic hybrid free standing film includes an organic polymer having a constitutional repeating unit derived from a monomer represented by general formula (1) and a hydrolytic condensate of a metal alkoxide.
