White-light emitting electroluminescent display device and manufacturing method thereof
 An improved white-light emitting electroluminescent display device and a manufacturing method thereof capable of advantageously generating a light having a red, blue, and green wave lengths within a unique material, which includes a substrate; a lower electrode disposed on the substrate; a first dielectric layer disposed on the lower electrode; a ZnS:Pr,Mn light-emitting layer disposed on the first dielectric layer; a second dielectric layer; and an upper electrode disposed on the second dielectric layer. In addition, a fabrication method thereof includes the steps of forming a first dielectric layer on an upper electrode; forming a light-emitting layer on the first dielectric layer by depositing a ZnS:Pr,Mn luminescent material made of Pr of 1.4.about.0.5 mol % and Mn of 0.1.about.0.01 mol % on a ZnS host material; forming a second dielectric layer on the light-emitting layer; and forming a lower electrode on the second dielectric layer.
