Laminated films, polarizers and liquid crystal displays |
| abstract |
The laminated film of the present invention includes a substrate and an optical function layer, the substrate includes a cellulose acylate having an acyl group substitution of 2.6 to 3.0 and a sugar ester in which 70 to 100% of the hydroxy groups are substituted with acyl groups, The slope obtained from the out-of-plane retardation at a wavelength of 650 nm and a wavelength of 450 nm is within a range of 0.040 to 0.055, the optical function layer contains a polymer containing fumaric acid ester polymerized units at a ratio of 90 mol% or more, and fumaric acid ester polymerized units 80 to 100% of the ester portion is isopropyl ester, and the value of the ratio of the out-of-plane phase difference between the wavelength of 450 nm and the wavelength of 550 nm of the laminated film is within the range of 1.1 to 1.9. |
