Abstract
Directed to a film having a depolarizing function, in which anisotropic volumetric regions are dispersed in a translucent matrix. For the translucent matrix, a material capable of forming a film itself, a hard coating layer formed on a surface of the film or a layer of an adhesive can be employed. It is therefore possible to provide a film, having a depolarizing function, of a kind in which when the film of the present invention is mounted on a surface of a polarizing plate arranged on a surface of a liquid crystal display device or an organic electroluminescent display device, the polarized state of a display light emerging outwardly from a display screen is partially altered and, hence, even when polarizing eyeglasses are worn on, darkening of the displayed image can be prevented and, also, a considerable shading of the color tone of the image can be reduced.
