Abstract

An organic light emitting display device includes a substrate, a display unit that is formed on the substrate, and includes a plurality of organic light emitting regions that emit light, a sealing member disposed above the display unit, and one or more light absorption pattern units formed on a plurality of non-light emitting regions of the display unit.

Claims

1. An organic light emitting display device comprising:

a substrate;

a display unit that is formed on the substrate, and comprises a plurality of organic light emitting regions that emit light;

a sealing member disposed above the display unit; and

one or more light absorption pattern units formed on a plurality of non-light emitting regions of the display unit.

2. The organic light emitting display device of claim 1, wherein the light absorption pattern units are formed to define each of the organic light emitting regions.

3. The organic light emitting display device of claim 1, wherein the light absorption pattern unit reduces light emitted from each of the organic light emitting regions from being mixed with each other.

4. The organic light emitting display device of claim 1, further comprising a black matrix formed on a surface of the sealing member to correspond to the non-light emitting region of the display unit.

5. The organic light emitting display device of claim 1, further comprising color filters formed on a surface of the sealing member to correspond to each of the organic light emitting regions.

6. An organic light emitting display device comprising:

a substrate;

a first electrode formed on the substrate;

a pixel defining layer that is formed on the first electrode, and exposes a portion of the first electrode;

an intermediate layer comprising an emissive layer, and formed on the exposed portion of the first electrode;

a second electrode formed on the pixel defining layer and the intermediate layer; and

a light absorption pattern unit formed on the second electrode to correspond to the pixel defining layer.

7. The organic light emitting display device of claim 6, wherein the light absorption pattern unit is formed to define the intermediate layer.

8. The organic light emitting display device of claim 6, wherein the light absorption pattern unit reduces light emitted from the intermediate layer from being mixed with each other.

9. The organic light emitting display device of claim 6, further comprising a black matrix formed on a surface of the sealing member to correspond to the pixel defining layer.

10. The organic light emitting display device of claim 6, further comprising a color filter formed on a surface of the sealing member to correspond to the pixel defining layer.

11. An organic light emitting display device comprising:

a substrate;

a first electrode formed on the substrate;

a pixel defining layer that is formed on the first electrode, and exposes a portion of the first electrode;

an intermediate layer comprising an emissive layer, and formed on the exposed portion of the first electrode;

a light absorption pattern unit formed on the pixel defining layer; and

a second electrode formed to cover the intermediate layer and the light absorption pattern unit.

12. The organic light emitting display device of claim 11, wherein the light absorption pattern unit is formed to define the intermediate layer.

13. The organic light emitting display device of claim 11, wherein the light absorption pattern unit reduces light emitted from the intermediate layer from being mixed with each other.

14. The organic light emitting display device of claim 11, further comprising a black matrix formed on a surface of the sealing member to correspond to the pixel defining layer.

15. The organic light emitting display device of claim 11, further comprising a color filter formed on a surface of the sealing member to correspond to the pixel defining layer.
