A transmissive-type organic electroluminescent display device includes a substrate including sub-pixel regions thereon, an array element in each sub-pixel area that includes thin film transistors, a partition wall at a border portion between adjacent sub-pixel regions made of a transparent insulating material, a first electrode made of a transparent conductive material in each sub-pixel region between adjacent partition walls, an organic electroluminescent layer on the first electrode in each sub-pixel region between the adjacent partition walls, a second electrode made of a transparent conductive material on the organic electroluminescent layer and a passivation layer covering the second electrode.
