Abstract

According to an embodiment of the present invention, an organic electroluminescent display device includes transistors formed on a substrate, an insulating layer on the transistors, a lower electrode formed on the insulating layer and coupled to a source or a drain of each of the transistors, a bank layer having openings to expose a part of the lower electrode, a bus electrode formed on the bank layer, an organic light-emitting layer formed to cover the lower electrode, the bank layer, and the bus electrode and patterned to expose at least a part of the bus electrode, and an upper electrode formed on the organic light-emitting layer and configured to come into contact with the exposed bus electrode.

Claims (18)

1. An organic electroluminescent display device, comprising:

transistors formed on a substrate;

an insulating layer on the transistors;

a lower electrode formed on the insulating layer and coupled to a source or a drain of each of the transistors;

a bank layer having openings to expose a part of the lower electrode;

a bus electrode formed on the bank layer;

an organic light-emitting layer formed to cover the lower electrode, the bank layer, and the bus electrode and patterned to expose at least a part of the bus electrode; and

an upper electrode formed on the organic light-emitting layer and configured to come into contact with the exposed bus electrode.

2. The organic electroluminescent display device according to claim 1 , wherein the bus electrode is in a shape of a mesh or stripes.

3. An organic electroluminescent display device, comprising:

transistors formed on a substrate;

an insulating layer on the transistors;

a lower electrode formed on the insulating layer and coupled to a source or a drain of each of the transistors;

a bus electrode formed on the insulating layer and separated from the lower electrode;

a bank layer having first openings to expose a part of the lower electrode and a second opening to expose at least a part of the bus electrode;

an organic light-emitting layer formed to cover the lower electrode, the bank layer, and the bus electrode and patterned to expose at least a part of the bus electrode; and

an upper electrode formed on the organic light-emitting layer and configured to come into contact with the exposed bus electrode.

4. The organic electroluminescent display device according to claim 3 , wherein the bus electrode is in a shape of a mesh or stripes.
