OPTICAL FILM, OPTICAL-FILM-PROVIDED POLARIZING PLATE, AND DISPLAY DEVICE

An optical film includes a low-refractive-index layer that includes a plurality of lens portions, and a high-refractive-index layer that fills a space between the plurality of lens portions. The lens portions each have a columnar shape and have a flat portion at an end thereof, and are arranged two-...

More Information
Summary:An optical film includes a low-refractive-index layer that includes a plurality of lens portions, and a high-refractive-index layer that fills a space between the plurality of lens portions. The lens portions each have a columnar shape and have a flat portion at an end thereof, and are arranged two-dimensionally. Distances between portions of the lens portions satisfy the following equation:((PA−((AIN+AEX)/2))×(PB−((BIN+BEX)/2)))/(PA×PB) is 0.42 or greater and 0.70 or less.
