Abstract
A compensating film capable of compensating both twist structure based on a liquid crystal cell and refractive index anisotropy to diminish the visual angle dependence of a liquid crystal display is provided. The film is formed using a discotic liquid crystalline material and the orientation form of the discotic liquid crystal is a twisted orientation.
Claims9
A liquid crystalline optical film having a fixed orientation form in the state of liquid crystal, characterized in that said film is formed of a discotic liquid crystalline material and that the orientation form of the discotic liquid crystal is a twisted orientation.
