OPTICAL ANISOTROPIC FILM AND LIQUID CRYSTAL DISPLAY APPARATUS

摘要

PROBLEM TO BE SOLVED: To find out a film manufacturing method capable of efficiently controlling the retardation in the thickness direction of a transparent film support small with respect to the average of the in-plane retardation thereof to obtain an inexpensive high performance optical anisotropic film by coating the produced film with a liquid crystal layer to orient the coated film and to provide a liquid crystal display apparatus using the optical anisotropic film. SOLUTION: An optical anisotropic film is constituted by providing at least one liquid crystal oriented film and at least one liquid crystal layer on a film support comprising fatty acid cellulose ester having a 2-3C acyl group and there is a relation represented by formula: (nx+ny)/2-nz>αbetween the in- plane refractive index nx in the x-direction, the refractive index ny in the y- direction and the refractive index nz in the thickness direction of the cellulose ester film support.
