Disclosed are an electroluminescent display device and a method of manufacturing the same. The electroluminescent display device includes a first bank on a substrate, an anode electrode extending to one side and another side of the first bank in an area exposed by the first bank, a second bank on each of one side and another side of the anode electrode, a light emitting layer on an upper surface of the anode electrode exposed by the second bank, and a cathode electrode on the light emitting layer. Since the anode electrode is provided on the first bank, the anode electrode is prevented from being damaged in a process of patterning the first bank. 公开了种电致发光显示装置及其制造方法。所述电致发光显示装置包括：位于基板上的第堤部；阳极电极，所述阳极电极从所述第堤部的侧延伸至另侧，以覆盖所述第堤部的每侧上的部分以及通过所述第堤部暴露的所述基板的区域；第二堤部，所述第二堤部定位成覆盖所述阳极电极的第侧和第二侧；发光层，所述发光层位于通过所述第二堤部暴露的所述阳极电极的上表面上；和位于所述发光层上的阴极电极。由于阳极电极设置在第堤部上，所以在将第堤部图案化的工艺中防止了阳极电极被损坏。
