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...

Zusammenfassung: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 nu RF is 1.10 or more. A phase difference elemental film composed of such a drawn film, or a phase difference plate which is composed of the drawn film and an optically isotropic film laminated at least on one side of the drawn film is used as the hue compensation of a liquid crystal display panel. Thereby, a liquid crystal display panel having no problem of coloring and the contrast ratio which have remained unsolved can be made.
