Abstract: An improved white-lite emitting electroluminescent display capable of emitting a light having a red, blue, and green wave length in a single material and having a buffer layer of Si.sub.x N.sub.y between a dielectric layer of BaTa.sub.2 O.sub.6 and a light-emitting layer, which includes a substrate; a lower dielectric layer of Bata.sub.2 O.sub.6 formed on a transparent electrode; a light-emitting layer of SrS:Pr,F formed on the lower dielectric layer; a buffer layer of Si.sub.x N.sub.y formed on the light-emitting layer; a upper dielectric layer of BaTa.sub.2 O.sub.6 formed on the buffer layer; and an upper electrode formed on the upper dielectric layer, and further includes the steps of a first step which forms a lower electrode on a substrate; a second step which forms a light-emitting layer of SrS:Pr.F on a lower dielectric layer; a third step which forms a buffer layer of Si.sub.x N.sub.y on the light-emitting layer; a fourth step which forms a upper dielectric layer of BaTa.sub.2 O.sub.
