OPTICAL COMPENSATION SHEET HAVING CELLULOSE ESTER FILM, ORIENTATION FILM AND OPTICAL ANISOTROPIC LAYER WITH FIXED ORIENTATION OF LIQUID CRYSTALLINE MOLECULES

摘要

An optical compensatory sheet comprises a cellulose ester film, an orientation layer and an optically anisotropic layer formed of liquid crystal molecules in this order. Alignment of the liquid crystal molecules is fixed. An alkaline solution is coated on a surface of the cellulose ester film to saponify the surface. The saponified surface is coated with a coating solution of the orientation layer.
