OPTICAL FILM, POLARIZING PLATE, AND IMAGE DISPLAY DEVICE |
| 摘要 |
An aspect of the invention relates to an optical film including a cellulose acylate film; and a hardened layer formed by hardening a curable composition, in which the cellulose acylate film includes polyester having a cyclic structure, the curable composition at least includes a granular filler, a polyester urethane having a tensile strength of 25 MPa or greater and a tensile elongation of 200% or greater, and a curable compound, and a content of the granular filler is in a range of 15 to 60 parts by mass and a content of the polyester urethane is in a range of 1 to 10 parts by mass, with respect to 100 parts by mass of a total amount of a solid content included in the curable composition, a polarizing plate, and an image display device. |
