OPTICAL COMPENSATING SHEET HAVING CELLULOSE ESTER FILM, ALIGNMENT FILM, AND OPTICALLY ANISOTROPIC LAYER COMPRISING LIQUID-CRYSTALLINE MOLECULES WITH FIXED ALIGNMENT

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.
