Abstract
An optical film composed by laminating a light scattering filmscattering and transmitting light and comprising at least two phases or more different in refractive index and a reflective polarizerselectively P/S converting the light. It is preferred that at least one phase of the light scattering film larger in the refractive index has a columnar structure extending in the thickness direction of the film and the transmittance of the film in the normal direction is 4% or more. The optical film is excellent in visibility, is small in light loss in order to provide an excellently visible and bright image, and has an excellent light collecting property when used in a liquid crystal display device or the like.
