| titleOfInvention | Optical film, polarizer and liquid crystal display |
| abstract | [Problems] nTo provide an optical film for a liquid crystal display that has good viewing angle compensation effects such as preventing color dropout (coloration) and achieving high contrast in all directions when used in a liquid crystal display. n[Means for solving problems] nAn optical film of the invention comprises at least one film (a) layer made of a cyclic olefin resin exhibiting positive birefringence and a film (b) layer made of a fluorene skeleton-containing polymer exhibiting negative birefringence laminated on said film (a) layer, and satisfies (1) 0.1 5 ≤ Nz-coefficient ≤ 0.9, (2) 0.5 ≤ R450/R550 ≤ 0.9, (3) 1.0 ≤ R650/R550 ≤ 1.3 and (4) 200 nm ≤ R550 ≤ 350 nm; wherein R450, R550 and R650 represent the retardation R at wavelengths of 450 nm, 550 nm and 650 nm, respectively. |
