OPTICALLY FUNCTIONAL FILM, PHASE DIFFERENCE FILM, COMPOSITION FOR FORMATION OF OPTICALLY FUNCTIONAL LAYER, AND METHOD FOR MANUFACTURE OF OPTICALLY FUNCTIONAL FILM

摘要

The main object is to provide an optically functional film which can exert excellent optical properties without the need of using any oriented film and has an excellent property of closely adhering to various layers and excellent display quality. The optically functional film comprises a substrate having properties required of an optically negative C-plate and an optically functional layer formed on the substrate and comprising a rod-shaped compound. The optically functional layer is formed on the substrate directly. The rod-shaped compound forms a random homogeneous orientation in the optically functional layer.
