Abstract
Disclosed is an optical compensation film made of a solution cast of a polymer blend comprising a nitrated styrenic fluoropolymer and a polyimide. The compensation film is a positive-C plate having reversed wavelength dispersion that is capable of providing an achromatic (or broadband) retardation compensation. The optical film of the invention can be used in an optical device such as liquid crystal display (LCD) or organic light emitting diode (OLED) display.
