摘要: The invention provides a long-bar-shaped anisotropic light diffusion film capable of enabling incident to generate in the direction orthometric with long side or nearby by using specified shutter structure and producing method for same. In containing structure, is formed multiple plate-shaped areas different refractive indexes, wherein indexes are arranged alternately any along surface. addition, when observed over film, an acute angle between extension less than 80 degrees.
