Patent ID: 8851951

Claim:
A method of fabricating an organic electroluminescent device, comprising: forming a switching element and a driving element connected to the switching element on a substrate in a pixel region; forming an overcoat layer on the switching element and the driving element with a contact hole defined therein to expose the driving element; forming a contact layer in the contact hole and on the overcoat layer, wherein the contact layer is made of a metallic material; forming a cathode on the contact layer, the cathode connected to the driving element through the contact layer; forming a passivation layer, including an opening, on the cathode, wherein edge portions of the contact layer and the cathode are covered by the passivation layer; forming an emitting layer on the cathode; and forming an anode on the emitting layer, wherein the contact layer is connected to the driving element through the contact hole in the overcoat layer, and wherein the contact hole is disposed in the opening.
