An illumination sign board using light emitting diodes is provided to illuminate an object to be illuminated in a lateral direction as well as a front surface, by uniformly distributing light over the entire surface of the object. An illumination sign board includes an object to be illuminated, a surface of the object being coated with a reflective layer(102), and a board(110) coupled to a rear surface of the object and having plural light emitting diodes. The reflective layer is coated on the entire surface of the object, so that light incident onto the object from the light emitting diodes is partially reflected by the reflective layer in the object, and is partially transmitted. |
