Patent ID: 8477267

Claim:
A process for manufacturing a light-condensing layered film, the light-condensing layered film comprising a light-condensing film and a long light-guiding film, the light-condensing film comprising an array of light collectors, the array of light collectors comprising an organic resin, the array of light collectors being disposed on a long light-diffusing film with a flexibility of 40 mm or less of a curvature radius and a coefficient of thermal expansion of 50 ppm/.degree. C. or less; the array of light collectors comprising a first surface and a second surface opposed to the first surface, the second surface contacting the long light diffusing film, the first surface being flat and having a smaller area than the second surface; wherein the long light-guiding film is laminated on the surface facing the light diffusing film in the light collector in the light-condensing film; the process comprising the steps of: filling a first irregularity in a support corresponding to a second irregularity for the array of light collectors with the organic resin to form the second irregularity made of the organic resin for the array of light collectors; transferring the second irregularity made of the organic resin from the support to the long light-diffusing thin film to form the array of light collectors, the array of light collectors; and laminating the long light-guiding film on the second surface of the array of light collectors exposing the second irregularity.
