Abstract
Disclosed is a multilayer optical compensation film comprising a first layer comprising a positive C-plate material and a second layer comprising a polyimide, as well as polymer compositions and resins and solutions containing said polymer compositions. The optical compensation film has a reversed wavelength dispersion that is capable of providing an achromatic (or broadband) retardation compensation. The optical film can be used in optical devices such as liquid crystal displays (LCD) or organic light emitting diode (OLED) displays.
