Optical film containing polymer having naphtyl group |
| abstract |
An optical film containing a polymer having at least a repeating unit represented by following general formula (I): n nThe optical film is excellent in heat resistance, transparency and processability because it contains a polymer having a naphthyl group in a molecular structure. In addition, when a retardation film is produced by drawing the optical film, a composition ratio of the polymer can be adjusted in a specific range so that the retardation film exhibits inverse wavelength dispersion properties such that higher retardation value is offered in measuring by light with longer wavelength. The retardation film having such properties is extremely useful for improving display properties of a liquid crystal display device. The optical film is also used in the production of a polarizing plate. |
