A billboard illuminated by optical fibers is realized by including a framework (1) having plurality outer surfaces (11) for display purpose, multiples optical fibers (2) provided within the framework (1) for guiding light from one surface (11A) to another (11B), and said optical fibers (2) are arranged in a matrix fashion with each optical fiber is spaced by a predetermined space (h) to form a figure or characters, a projecting device (3) placed away from the framework (1) by a predetermined distance (W) as light source, and a cladding (4) applied onto outer surfaces (11) for reinforcing the junction portion where the optical fiber (2) exposed from the outer surfaces (11).
