ABSTRACT:
A conductive paste capable of effectively preventing current interruption in through-holes of a fluorescent display device. An anode substrate having Al film wirings formed thereon is laminatedly provided thereon with an insulating layer, which is then formed thereon with an anode conductor and phosphor layers in turn, leading to an anode. The insulating layer is formed with through-holes, in which the conductive paste is filled to make electrical connection between the wirings and the anode conductors. The conductive paste is formed of a mixture of Ag, glass and a vehicle, and Zn and/or Sb added to the mixture, wherein Zn and/or Sb are added to the mixture in an amount of 1 to 40 wt. % based on Ag. Zn and/or Sb serve as a catalyst for promoting alloying between Ag contained therein and Al, resulting in providing electrical connection therebetween with highly increased stability.
