A color electroluminescence(EL) display element and the manufacturing method thereof which can improve an RC-time delay phenomenon and the contrast of the EL display element. According to the EL display element, an auxiliary metal electrode is formed on a transparent electrode. The auxiliary metal electrode is formed by forming on the transparent electrode a metal film having a high melting point and a low resistivity, such as molybdenenum, with a thickness of about 1000 .ANG., and then by selectively etching the metal film so that it remains on the boundary between each of R, G, and B color filters with a width of about 5 to 30 .mu.m. The color filters are formed on a circular polarizing plate and sealed up with the auxiliary metal electrode, and thus the circular polarizing plate absorbs an external light incident to and reflected from a metal electrode.

There is provided a method for the fabrication of multilayer electroluminescence device, comprising the steps of: forming a lower electrode with a predetermined pattern on a substrate: forming a first insulation layer on the lower electrode atop the substrate; forming a multiply luminescent layer consisting of CaS and SrS on the first insulation layer at the same temperature with that for the first insulation layer; forming a second insulation film on the luminescent layer; and forming an upper electrode with a predetermined on the second insulation layer. In the multiply luminescent layer, a plurality of CaS plies and a plurality of SrS plies are formed in such a way that the CaS plies and the SrS plies alternate with each other and the outmost upper and lower plies are formed of CaS. The constituent substances for the multiply luminescent layer, CaS and SrS, can be deposited at the same temperature and have similar lattice constants which can lead to a matched interface between the CaS and SrS plies. By virtue of these advantages, stresses imposed on the interface, including thermal stress, can be significantly reduced. In addition, the matched interface makes electrons be accelerated with large energy, so that the fabricated multilayer luminescence device may show good quality.

An electroluminescent panel has a light emitting body sealed in an inner space between transparent package films, and the light emitting body includes a fluorescent layer, a transparent electrode formed on one surface of the fluorescent layer and formed of indium tin oxide and a back electrode formed on the other surface of the fluorescent layer and formed of aluminum, wherein the light emitting body is folded down so that a non-transparent conductive layer of silver is patterned on the transparent electrode of the folded portion, thereby enhancing the uniformity of brightness by virtue of the light radiated from the folded portion.
