| titleOfInvention | Retardation film, polarizing plate and liquid crystal display device |
| abstract | Provided is a retardation film that improves the viewing angle of an IPS liquid crystal display device in which fluctuations in optical characteristics due to environmental changes are small. The first optical anisotropic layer includes at least a first optical anisotropic layer and a second optical anisotropic layer, the in-plane retardation Ro of the first optical anisotropic layer is 0 to 10 nm, and the thickness is The retardation Rt in the direction is −400 to −80 nm, and the second optically anisotropic layer contains a cellulose ester in which a hydroxyl group of cellulose is substituted with an acetyl group and an acyl group having 3 to 5 carbon atoms. A cellulose ester film having a thickness of 20 to 50 μm, wherein the substitution degree A of acetyl group and substitution degree B of acyl group having 3 to 5 carbon atoms satisfy the following formulas (I) and (II), A retardation film having a retardation Ro of 20 to 150 nm and a thickness direction retardation Rt of 100 to 300 nm. Formula (I): 2.0 ≦ A + B ≦ 3.0 Formula (II): 0 <B [Selection figure] None |
