SPONTANEOUS LIGHT POINTER, MANUFACTURING METHOD FOR SPONTANEOUS LIGHT POINTER AND DISPLAY DEVICE FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a spontaneous light pointer with easy assembling in a rotation shaft. SOLUTION: The arrangement comprises a pointer main body 11 which is formed in one body with a base part 12 electrically connected and attached to the tip end of the rotation shaft 31 and a pointing part 13 connected from the base part 12, and an electrode member 15 electrically connected with a terminal provided on the back surface of a dial plate when the base part 12 is attached to the rotation shaft 31 and placed to the base part 12 of the pointer body 11 in a state insulated from the pointer body 11. On the surface of the pointing part 13, a dielectrics insulation layer 16 and fluophor emission layer 17 are formed by piling in turn. The pointing part 13 is formed with an electroluminescence element by forming a transparent conduction film 18 so as to cover the surface of the dielectrics insulation layer 16 and the fluophor emission layer 17. Accordingly to electric current to the pointer body 11 electrically connected with the rotation shaft 31 and the electrode member 15 electrically connected with the terminal 40, the pointing part 13 of the spontaneous light pointer 10 emits light excited by the light emitted by the fluophor emission layer 17.
