Abstract
Disclosed is a liquid crystal display device wherein an optically anisotropic layer is formed on an optical film satisfying that Rth is 0 to 150 nm at 23° C./60% RH and the difference between Rth at 23° C./10% RH and Rth at 23° C./80% RH is 40% or less of Rth at 23° C./60% RH. In the liquid crystal display, liquid crystal cells are optically compensated accurately and less affected in the display properties even when the storage environment changes.
