Abstract

An organic light emitting diode display includes a substrate, a first electrode, a second electrode, an organic emission layer positioned between the first electrode and the second electrode, a driving voltage line, a dummy electrode. The dummy electrode is positioned at the same layer as the first electrode.

Claims (40)

1. An organic light emitting diode display comprising:

a substrate including a display area, a driving circuit area, and a dummy region positioned between the display area and the driving circuit area;

a first electrode positioned in the display area;

a second electrode overlapping the first electrode and configured to receive a common voltage;

an organic emission layer positioned between the first electrode and the second electrode;

a driving voltage line positioned in the display area and the dummy region; and

a dummy electrode positioned in the dummy region and connected to the driving voltage line and configured to receive a driving voltage,

wherein the dummy electrode is positioned at the same layer as the first electrode, and

wherein the dummy electrode and electrically insulated spaced apart from each other.

2. The organic light emitting diode display of claim 1 , wherein

the dummy electrode is made of the same material as the first electrode.

3. An organic light emitting diode display comprising:

a substrate including a display area, a driving circuit are and a dummy region positioned between the display area and the driving circuit area;

a first electrode positioned in the display area;

a second electrode overlapping the first electrode;

an organic emission layer positioned between the first electrode and the second electrode,

a driving voltage line positioned in the display area and the dummy region;

a dummy electrode positioned in the dummy region and connected to the driving voltage line, wherein the dummy electrode is positioned at the same layer as the first electrode; and

a plurality of openings formed in the dummy electrode.

4. The organic light emitting diode display of claim 3 , wherein

the plurality of openings are disposed with a predetermined interval.

5. The organic light emitting diode display of claim 1 , further comprising a pixel definition layer positioned between the dummy electrode and the second electrode.

6. The organic light emitting diode display of claim 5 , wherein

the pixel definition layer is further positioned between the first electrode and the second electrode.

7. The organic light emitting diode display of claim 6 , wherein

the pixel definition layer is formed on an edge portion of the first electrode.

8. The organic light emitting diode display of claim 5 , wherein

the pixel definition layer includes polyacrylate resin, a polyimide resin, a silica-based inorganic material, a silicon nitride.

9. The organic light emitting diode display of claim 5 , further comprising

a spacer positioned between the pixel definition layer and the second electrode.

10. The organic light emitting diode display of claim 9 , wherein

the spacer is positioned between the dummy electrode and the second electrode.

11. The organic light emitting diode display of claim 9 , wherein

the pixel definition layer and the spacer are integrally made.

12. The organic light emitting diode display of claim 1 , further comprising

a passivation layer positioned between the driving voltage line and the dummy electrode,
