摘要:
A fluorescent display device is disclosed. The fluorescent display device includes an anode plate, aluminum anode wirings arranged on the anode plate, a first light shielding aluminum film arranged on the anode plate, an insulation layer arranged on both the anode wiring and the first light shielding film, a second light shielding graphite film arranged on the insulation layer, an anode electrode arranged on the insulation layer, and an outer light source display formed by removing a portion of the first light shielding film. The outer light source display is illuminated by a LED to display a predetermined pattern. The second light shielding film is formed along a wiring array arranged on the first light shielding film and the wiring so that a gap between the first light shielding film and the wirings is covered with the second light shielding film.
