发明名称 ANISOTROPIC LIGHT-DIFFUSING FILM, ANISOTROPIC LIGHT-DIFFUSING LAMINATE, ANISOTROPIC LIGHT-REFLECTING LAMINATE, AND USES THEREOF
摘要 An anisotropic light-diffusing film, an anisotropic light-diffusing laminate, and an anisotropic light-reflecting laminate are provided which are excellent in both light transmittance and diffusivity. Also provided are a lighting equipment and a display device which employ any of the film and laminates and are excellent in light-diffusivity and brightness and in economy, etc. The anisotropic light-diffusing film is a film formed by melt-extruding a mixture of at least two thermoplastic resins incompatible with each other. The film has parallel light ray transmittance of 20-85%, haze of 10-80%, glossiness of 10-70%, and ratio of the vertical-direction diffusivity to the horizontal-direction diffusivity of transmitted light of 1.3-6.0. The anisotropic light-reflecting laminate comprises a light reflector and the anisotropic light-diffusing film laminated over at least one surface of the reflector. In the laminate, diffusivity ratio, reflectivity and diffusivity of reflected light satisfy respective specific ranges.
