Abstract
A fluorescent display device includes an aluminum wiring layer formed on an insulating substrate; an insulating layer formed on the aluminum wiring layer, the insulating layer being provided with a through-hole disposed on the aluminum wiring layer; a conductive layer filled in the through-hole. The fluorescent display device further includes an anode conductor formed on the insulating layer to cover the conductive layer and a phosphor layer formed on the anode conductor. The conductive layer is formed of solid mixture containing aluminum and graphite.

A fluorescent display device comprising:
- an aluminum wiring layer formed on an insulating substrate;
- an insulating layer formed on the aluminum wiring layer, the insulating layer being provided with a through-hole disposed on the aluminum wiring layer;
- a conductive layer filled in the through-hole;
- an anode conductor formed on the insulating layer to cover the conductive layer;
- and a phosphor layer formed on the anode conductor, wherein the conductive layer is formed of a solid mixture containing aluminum and graphite, wherein the aluminum is prevented from being oxidized by the graphite serving as a reducing agent for the aluminum, and wherein the conductive layer is formed of the solid mixture which contains aluminum in a range from 99.99 to 60 weight % and graphite in a range from 0.01 to 40 weight % of the total weight of aluminum and graphite of the solid mixture.
