发明名称 Luminous pointer and manufacturing method thereof
摘要 An insulating layer, a luminescent layer, a transparent electrode, base sheet with a transparent electrode formed thereon and a desiccant film are laminated in that order on the upper surface of a pointer body which also serves as a rear electrode. The upper surface of the dessiccant film is sealed with a moistureproof film. In producing a luminous pointer, these layers are laminated at a plurality of portions on the upper surface of a sheet which is to constitute pointer bodies, the pointer bodies are blanked along the outlines thereof by press working, and then the outside of the disiccant film is sealed with a moistureproof film. Alternatively, the outside of the desiccant film may be sealed with a moistureproof film before blanking the pointer bodies by press working.
