Directional light-diffusing film, a method of manufacturing same, and a display device that uses same |
摘要 |
A directional light-diffusing film is formed by minute light-transmitting regions which pass light and minute light-diffusing regions which diffuse light, these light-transmitting regions and light-diffusing regions being arranged in an alternating pattern on a surface of a transparent base material film in either the direction of one dimension or the direction of two dimensions. Light which passes through the light-diffusing regions is diffused, while light that passes through the light-transmitting regions is transmitted without diffusion, and when this directional light-diffusing film is mounted to the light-exiting surface of a liquid-crystal display or the like, there is an increase in the amount of undiffused light that reaches the eye, and prevention of defocusing of the display image.
