RETARDATION FILM, POLARIZING PLATE, LIQUID CRYSTAL DISPLAY DEVICE, AND METHOD FOR PRODUCTION OF RETARDATION FILM

摘要

Disclosed is a retardation film which comprises a cellulose derivative and a plasticizer, and has the following total haze value (Htotal): 0.1% <= Htotal <= 0.4% and a ratio of an internal haze value (Hi) to the total haze value (Htotal) (i.e., an Hi/Htotal ratio) of 0.5 or less as measured on a single sheet of film. Total haze value (Htotal): a haze value (%) measured in accordance with JIS K7136 (which is equivalent to ISO14782:99). Internal haze value (Hi): a value (%) determined by subtracting a haze value (%) measured on only two glass plates each having a thickness of 1.3 mm after dripping several drops of glycerin between the glass plates from a haze value (%) measured on a film sandwiched by the two glass plates after dripping several drops of glycerin on the surface of the film and then sandwiching the film between the two glass plates.
