发明名称 Optical Anisotropic Film, Process for Producing the Same and Liquid Crystal Display Using the Same
摘要 <p>Disclosed is an optically anisotropic film used for a liquid crystal display of a vertical alignment liquid crystal mode comprising a fatty acid cellulose aster film, a retardation value (Rt value) in the thickness direction of the fatty acid cellulose ester film is from 60 to 300 nm, and the number of luminescent points having a size exceeding 50μm is zero per 250 mm2, and the number of luminescent points having a size of 5 to 50μm is 200 or less per 250 mm2 when the fatty acid cellulose ester film is observed with two polarizing plates being provided on both surfaces of the fatty acid cellulose ester film so as to shield transmission light.</p>
