| titleOfInvention | Cellulose ester film |
| abstract | An object of the present invention is to provide a polarizing plate protective film capable of detecting and judging grain-like foreign matter by a simple method, and further improve the appearance of a polarizing plate manufactured using the same, and also manufactured using the polarizing plate. Provided is a cellulose ester film capable of improving the visibility of a liquid crystal display (liquid crystal display device). SOLUTION: A cellulose ester film having a thickness of 20 to 60 μm used for a protective film for a polarizing plate or the like has 50 or less foreign substances having an average particle diameter of 10 μm or more per area of 0.9576 mm 2 , and an average particle diameter of 50 or less. The number of foreign substances having a size of less than 10 μm is 200 or less. In addition, a foreign matter having an average particle diameter of 20 μm or more per area of 0.9576 mm 2 of the cellulose ester film is a, foreign matter having an average particle diameter of 10 μm to less than 20 μm is b, and foreign matter having an average particle diameter of less than 10 μm is c. At this time, the following relational expression holds. 4a + b + (1/9) c ≦ 100 [Selection diagram] None |
