A film of 15 to 45 μm thick containing a cellulose acylate and an aromatic ester oligomer having a repeating unit derived from a dicarboxylic acid and a repeating unit derived from a diol, in which the repeating unit derived from a dicarboxylic acid has a ratio m/n of from 0/10 to 3/7, m and n represent a molar proportion of a repeating unit derived from an aliphatic dicarboxylic acid and an aromatic dicarboxylic acid, respectively, and the film satisfies |Rth(590)|≦50 nm; has a good appearance and is free of deterioration in display performance when the film with a thin thickness is produced in the form of a roll, achieves a high pencil hardness by imparting a high Knoop hardness to the film, even with a hard coat layer provided, and is free of display unevenness on installing the film in a liquid crystal display device.
一种厚度为15至45μm的薄膜,包含纤维素酰酸酯和芳香酯低聚物,其重复单元由二元羧酸和二元醇衍生而来,其中由二元羧酸衍生的重复单元具有m/n比率为0/10至3/7,m和n分别表示由脂肪族二元羧酸和芳香族二元羧酸衍生的重复单元的摩尔比例,且薄膜满足| Rth(590)|≦50nm; 在以卷的形式生产薄膜时,具有良好的外观并且不会损害显示性能,即使提供了硬质涂层层,也能实现高铅笔硬度,且在将薄膜安装在液晶显示器件中时,不会出现显示不均匀的情况。
