  • Patent number: 5384882
    Abstract: In the image display device of the present invention, a number of light scattering layers formed on the ends of optical fibers are spotwise distributed on the image display surface, and said scattering layers are comprised of a transparent resin having a granular light scattering material added or very small depressions and projections produced on the surface. Further, the method of manufacturing the image display device according to the present invention is characterized by arranging the end faces of a number of optical fibers to the image display surface, then applying a photosensitive resin onto the image display surface, hardening the resin around the end of the respective optical fibers on the image display surface by the beam of light from the incident surface to form light scattering layers, then removing the unhardened portions.
