CELLULOSE ESTER FILM, PRODUCTION METHOD THEREFOR, POLARIZING PLATE PROVIDED THEREWITH, AND LIQUID CRYSTAL DISPLAY

摘要

Provided are a cellulose ester film with high transmittance, and a production method therefor. Further, provided are a polarizing plate provided with the cellulose ester film, and a liquid crystal display with high contrast. This cellulose ester film contains a cellulose ester including an acyl group having 2 to 4 carbon atoms, and the substitution degree of the acyl group is 2.0 to 2.5. The cellulose ester film is characterized in that the number of foreign bodies having a diameter translated into circle in the range of 60 to 100 µ is 10 pieces or less per 10 cm2, the number of foreign bodies having a diameter translated into circle in the range of 10 to 50 µ is 10 pieces or less per 10 cm2, the internal haze is 0.1 or less, and the thickness is in the range of 20 to 50 µm.
