| 摘要 |
The disclosed retardation film contains a layer comprising a resin composition containing 30-95 wt% of a (meth)acrylate polymer having a ring structure at the backbone, and 5-70 wt% of a cellulose ester polymer. The retardation film has low moisture permeability and a low photoelastic coefficient, and has a high degree of freedom of controlling retardation wavelength dispersion; for example the film exhibits a retardation reverse wavelength dispersion, or has a flat retardation wavelength dispersion. The retardation film is suitable for optical compensation applications in an image display device such as a liquid crystal display (LCD) device. |
