Abstract

An organic light-emitting display device including: a substrate including a pixel region and a non-pixel region; a first electrode formed on the pixel region in a first direction; a first wire coupled to the first electrode and formed in the non-pixel region; a second electrode formed in the pixel region in a second direction; a second wire coupled to the second electrode and formed in the non-pixel region; an organic thin film layer formed between the first electrode and the second electrode; a drive circuit coupled to the first wire and the second wire; and a passivation layer formed across the pixel region and the non-pixel region and having an opening to expose at least one of the first wire and the second wire.

Claims (27)

1. An organic light-emitting display device, comprising: a substrate having a pixel region and a non-pixel region; first electrodes disposed in the pixel region and extending in a first direction; first wires coupled to respective ones of the first electrodes and disposed in the non-pixel region; second electrodes disposed in the pixel region, and extending in a second direction; second wires coupled to respective ones of the second electrodes and disposed in the non-pixel region; an organic thin film layer disposed between the first and second electrodes; a drive circuit located in the non-pixel region and coupled to the first and second wires; and a passivation layer formed on the substrate, having an opening to expose a plurality of the first wires to couple a short bar for electrically connecting the plurality of first wires during testing; wherein the first wires extend from the drive circuit to the first electrodes, and wherein the opening is formed above at least a portion of the plurality of the first wires.

2. The organic light-emitting display device according to claim 1 , wherein the first wires and the second wires each comprise a transparent electrode and an auxiliary electrode disposed on the transparent electrode.

3. The organic light-emitting display device according to claim 1 , wherein the passivation layer comprises a material selected from the group consisting of a polyimide, a phenol resin, and an acrylic resin.

4. The organic light-emitting display device according to claim 1 , wherein the passivation layer is disposed between the first electrodes and the second electrodes.

5. The organic light-emitting display device according to claim 1 , further comprising an input pad formed in the non-pixel region, coupled to an input terminal of the drive circuit, and exposed through a second opening formed in the passivation layer.

6. The organic light-emitting display device of claim 1 , wherein the short bar is disposed in the opening and connected to the first wires.

7. The organic light-emitting display device according to claim 2 , wherein:

the transparent electrode comprises a material selected from the group consisting of indium tin oxide (ITO), indium zinc oxide (IZO), and indium tin zinc oxide (ITZO); and

the auxiliary electrode comprises a material selected from the group consisting of aluminum (Al), silver (Ag), molybdenum (Mo), copper (Cu), and chromium (Cr).

8. The organic light-emitting display device according to claim 2 , wherein the auxiliary electrode comprises two or more layers that each comprise a metal independently selected from the group consisting of aluminum (Al), silver (Ag), molybdenum (Mo), copper (Cu), and chromium (Cr).

9. An organic light-emitting display device, comprising:

a substrate having a pixel region and a non-pixel region;

first and second electrodes disposed in a matrix in the pixel region;

scan lines disposed in the non-pixel region and coupled to the first electrodes;

data lines disposed in the non-pixel region and coupled to the second electrodes;

an organic thin film layer formed between the first electrodes and the second electrodes;

a drive circuit located in the non-pixel region and coupled to the scan and data lines; and

a passivation layer formed on the substrate, having first and second openings to respectively connect a plurality of the scan lines, or a plurality of the data lines, to a short bar during testing,

wherein the scan lines extend from the drive circuit to the first electrodes,

wherein the data lines extend from the drive circuit to the second electrodes, and

wherein the first and second openings are respectively formed over at least a portion of the plurality of the scan lines and the plurality of the data lines.

10. The organic light-emitting display device of claim 9 , wherein the scan and data lines each comprise an auxiliary electrode and a transparent electrode disposed on the auxiliary electrode.

11. The organic light-emitting display device of claim 9 , further comprising an input pad disposed in the non-pixel region, coupled to an input terminal of the drive circuit, and exposed through an opening formed in the passivation layer.

12. The organic light-emitting display device of claim 9 , wherein:

the passivation layer comprises a material selected from the group consisting of a polyimide, a phenol resin, and an acrylic resin; and

the scan and data lines each comprise an auxiliary electrode and a transparent electrode disposed on the auxiliary electrode.

13. The organic light-emitting display device of claim 9 , wherein the passivation layer is disposed between the first and second electrodes and comprises a material selected from the group consisting of a polyimide, a phenol resin, and an acrylic resin.
