Phase difference film, polarizing plate using such phase difference film, and image display device |
| abstract |
An aspect of the present invention relates to an optical film comprising a cellulose ether derivative and a compound having negative intrinsic birefringence and having a transmittance of 89% or more at a wavelength of 320 nm to 400 nm and an in-plane retardation (Ro 550 ) at a wavelength of 550 nm of 115 nm or more and 160 nm or less, and the wavelength ratio of the in-plane retardation (Ro 450) at 450nm (Ro 450 / Ro 550) is 0.72 or more to 0.94 or less for the phase difference film 550 Ro. |
