ABSTRACT:
A method for manufacturing an electroluminescence display having a multi-layered substrate is disclosed. The multi-layered substrate includes a transparent electrode layer, a lower dielectric layer, a luminescent layer, an upper dielectric layer, a black layer and a rear electrode layer stacked successively on a substrate. The method requires coating an Al layer on the upper dielectric layer by placing the multi-layer coated substrate under a lower vacuum atmosphere containing a predetermined gas to form the black layer by a reaction between Al and the gas. Another Al layer is coated on the black layer under a higher vacuum atmosphere vacuum atomosphere and then baked. The baked Al layer is then etched to form the rear electrode layer.
