1. An organic electroluminescent display device comprising:
a driving thin film transistor in a pixel region of a first substrate;
a first electrode on a second substrate opposite to the first substrate;
a separator on the second substrate to define a contact part on the second substrate;
an organic common layer on the first electrode within the contact part and outside the contact part;
an organic luminescent layer on the organic common layer outside the contact part;
an electron injection layer on the organic luminescent layer;
a second electrode on the electrode injection layer within the contact part and on the organic luminescent layer; and
a connection electrode connecting the driving thin film transistor to the second electrode.
