Abstract

This invention relates to an optical film with both light-diffusion and brightness-enhancement effects. It possesses a light incidence surface, and a light outgoing surface. The light outgoing surface has a first refraction part of which the cross section has a first arc-shaped surface, and a second arc-shaped surface. There is a second refraction part between the first and the second arc-shaped surfaces. The second refraction part has a first oblique surface and a second oblique surface. It intersects with each other on the light incidence side, and forms an angle. It provides the effects of both light-diffusion, and brightness-enhancement, and increases the yield rate of production. The luminance can be increased for more than 1.55 times.
