PROBLEM TO BE SOLVED: To easily connect an optical fiber, to cancel a nonuniformity of a bent of an optical fiber and to surely transfer light by arranging a bundling part of an optical fiber in almost a middle part of a mark at the time of introducing the light of a light emitting body emitted by a sollar battery through an optical fiber and forming a mark. SOLUTION: In a display device provided with a light emitting body (LED) 20 emitted by receiving a generated electric power of a sollar battery 10, a marking part 18 introducing light from LED 20 to a light emitting end 32 through an optical fiber 30 and forming a prescribed mark, the bundling part 73 of the optical fiber 30 connected to the LED 20 is arranged in almost a middle part of the mark of the marking part 18. A distance between the bundling part 73 and the marking part 18 hardly becomes different even when the shape of the mark is complicated and closely united wiring state is obtained. Since more than an allowable curvature of the optical fiber is ensured, the bent of the optical fiber is made almost uniform, light is surely transferred and the mark is exactly displayed. |
