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.degree. C./60% RH and the difference between Rth at
23.degree. C./10% RH and Rth at 23.degree. C./80% RH is 40% or less of
Rth at 23.degree. 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.
