An electroluminescent display (EL) device and a method of manufacturing the same. The EL device includes a substrate, a first electrode unit including first electrodes formed on the substrate in a predetermined pattern, and first electrode terminals connected to the respective first electrodes; a second electrode unit including second electrodes formed on the first electrodes, and second electrode terminals connected to the respective second electrodes; 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, and 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 to reduce a steepness of a step between the second electrode terminal and the substrate.
