Patent ID: 8858286

Claim:
A method for fabricating an organic electroluminescent display device, comprising: forming a switching thin film transistor, a driving thin film transistor and an organic electroluminescent diode on a mother substrate having a plurality of unit cell areas; forming a cutting portion in a metal foil having a plurality of unit metal foil areas, the metal foil having a size corresponding to the mother substrate; forming an adhesive layer on the metal foil; attaching the mother substrate and the metal foil such that the adhesive layer contacts the mother substrate; and cutting the mother substrate and the metal foil along the cutting portion, wherein forming the cutting portion in the metal foil comprises removing the metal foil along four sides of each of the plurality of unit metal foil areas between the adjacent unit metal foil areas except for a plurality of connecting portions each connecting the adjacent unit metal foil areas by an etching method.
