摘要： 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. With the image display device thus obtained, an image is transmitted via a number of optical fibers and displayed via a number of light scattering layers, and so a wide angle is provided for the field of vision, and also with the dark colored ground, it is possible to reduce the reflection of the light of disturbance at portions other than the light scattering layers and thus display a clear image of high contrast.
