1. A method of fabricating an organic electroluminescent display device, comprising:

  • forming a thin film transistor on a first substrate having a plurality of sub-pixel regions, the thin film transistor corresponding to each of the plurality of sub-pixel regions;

    forming a passivation layer on the thin film transistor, the passivation layer having a contact hole exposing the thin film transistor;

    forming a connection pattern on the passivation layer, the connection pattern contacting the thin film transistor through the contact hole and having a first portion contacting the second electrode and a second portion adjacent to the first portion such that a cross sectional area of the first portion is larger than a cross sectional area of the second portion;

    forming a first electrode on a second substrate having the plurality of sub-pixel regions;

    forming an organic electroluminescent layer on the first electrode;

    forming a second electrode on the organic electroluminescent layer, the second electrode corresponding to each of the plurality of sub-pixel regions; and

    attaching the first and second substrates such that the connection pattern contacts the second electrode,wherein a melting temperature of the connection pattern is lower than a melting temperature of the second electrode.
