Abstract:
1. An electroluminescent display EL device comprising: a substrate; a first electrode unit comprising: an emission area formed where the first electrodes intersect the second electrodes; an electroluminescent layer disposed between the first electrodes and the second electrodes in the emission area; an inter insulating layer provided under the electroluminescent layer and covering a space between each of the plurality of lines of the first electrodes and an edge portion of a top surface of each of the plurality of lines of the first electrodes; an outer insulating layer between the emission area and the second electrode terminals, wherein the outer insulating layer comprises an insulating material formed to contact at least an edge of the second electrode terminals facing the emission area so as to reduce a steepness of a step between the second electrode terminals and the substrate; and a buffer layer provided over a top surface of the substrate to maintain smoothness of the top surface of the substrate and to prevent impurities from being introduced from the substrate.
