Abstract:
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.
