PROBLEM TO BE SOLVED: To obtain a device which has high lighting efficiency, generates no lighting irregularity, and does not require a lens for projection on a document by reading an image by an organic light emission source formed by sandwiching a light emission layer of an organic compound constituted in molecular structure between an anode and a cathode on a flexible printed wiring board. SOLUTION: The organic light emission source 5d is formed on the flexible printed wiring board 51 and light emission parts corresponding to the primary colors R, G, and B are arrayed alternately. Each light emission part has an anode 52 made of ITO, etc., and a cathode 54 made of AL, etc., a thin organic light emission layer 53 made of an organic compound is sandwiched between both electrodes, and a protection layer 55 is formed lastly by coating. The printed wiring board 51 has an oblong hole 51a along the length at a nearly center part and on both sides of the oblong hole 51a, organic light emission sources 5d are arrayed at the same positions. Further, the printed wiring board 51 has tabs. |
