Abstract: An electroluminescent display device is disclosed. The electroluminescent display device includes a substrate having thereon a first sub pixel and a second sub pixel, a first electrode in each of the first sub pixel and the second sub pixel on the substrate, an organic layer with P-type polarity or N-type polarity on the first electrode, and a second electrode on the organic layer. The organic layer provided in the first sub pixel and the organic layer provided in the second sub pixel are spaced apart from each other with a doping layer provided in the boundary area between the first sub pixel and the second sub pixel. The doping layer is doped with dopant whose polarity is opposite to that of the organic layer.
