Light-condensing film, liquid-crystal panel and backlight as well as manufacturing process for light-condensing film

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.
