PHASENDIFFERENZ-FILM, PHASENDIFFERENZ-PLATTE UND FLÜSSIGKRISTALLANZEIGE

A drawn film is obtained by drawing at least monoaxially a polymer film which has a refraction factor nD higher than 1.60 an Abbe number nu D larger than 30.0 and a glass transition point Tg ranging from 60 to 160 DEG C. The retardation value R of the drawn film is 6-1000 nm and the dispersion value...
