<P>PROBLEM TO BE SOLVED: To provide an optical polyester film which has excellent travellability and scratch resistance while holding high transparency, can be improved in the planarity of the film by improving drawability of the film, and is suitable for the field of displays. <P>SOLUTION: The optical polyester film has a substrate layer composed of a biaxially oriented polyester, and an adhesive layer easily adhered at least on one surface of the substrate layer. The substrate layer contains fine particles having an average particle diameter of 0.03 to 0.50 μm, and the substrate layer further contains particles having an average particle diameter of 1.0 to 10.0 μm, so that a desired optical polyester film can be produced. <P>COPYRIGHT: (C)2012,JPO&INPIT |
