An optical film having low moisture permeability and improved dimensional stability, such as a polarizing plate protective film and a retardation film, and a retardation film that suppresses retardation fluctuation of the retardation film and has excellent durability. , An antireflection film and a method for producing the same. An organic-inorganic hybrid film containing, as a main component, a polycondensate of a cellulose derivative and a reactive metal compound capable of hydrolysis and polycondensation, wherein the film contains 1 to 20% by mass of a plasticizer. An organic-inorganic hybrid film characterized by the following. [Selection] Fig. 2 |
