Abstract

An organic light emitting display apparatus that includes a substrate, an organic light emitting unit formed on the substrate, a reflection member disposed on a non-light emitting region of the organic light emitting unit, and a sealing member that seals the organic light emitting unit. The organic light emitting display apparatus can function as a display apparatus or a mirror.

Claims (48)

1. An organic light emitting display apparatus comprising:

a substrate;

an organic light emitting unit on the substrate;

a reflection member at a non-light emitting region of the organic light emitting unit; and

a light absorption layer on a surface of the reflection member facing the organic light emitting unit.

2. The organic light emitting display apparatus of claim 1 , further comprising a sealing member that seals the organic light emitting unit,

wherein the sealing member is separately disposed from the organic light emitting unit.

3. The organic light emitting display apparatus of claim 2 , further comprising a combining member that joins the substrate and the sealing member.

4. The organic light emitting display apparatus of claim 3 , wherein the combining member is disposed along edges of the substrate.

5. The organic light emitting display apparatus of claim 3 , wherein the combining member further comprises spacers and a sealant.

6. The organic light emitting display apparatus of claim 1 , further comprising a sealing member that seals the organic light emitting unit,

wherein the reflection member is on a surface of the sealing member that faces the organic light emitting unit to correspond to the non-light emitting region of the organic light emitting unit.

7. The organic light emitting display apparatus of claim 1 , wherein the reflection member comprises a material that reflects light proceeding towards the reflection member from outside of the organic light emitting display apparatus.

8. The organic light emitting display apparatus of claim 7 , wherein the reflection member comprises a metal that reflects light proceeding towards the reflection member from outside of the organic light emitting display apparatus.

9. The organic light emitting display apparatus of claim 1 , wherein the reflection member comprises Al.

10. The organic light emitting display apparatus of claim 9 , wherein the reflection member has a thickness of 250 .ANG. or more.

11. An organic light emitting display apparatus comprising:

a substrate;

a plurality of pixel electrodes on the substrate;

a pixel defining layer on the pixel electrode and exposing a portion of each of the pixel electrodes;

an intermediate layer comprising a light emitting layer on each of the exposed pixel electrodes;

a reflection member on the pixel defining layer between adjacent ones of the light emitting layers; and

a facing electrode covering the intermediate layer and the reflection member,

wherein the light emitting layer is offset from the reflection member in a direction parallel to the substrate, and

wherein the reflection member is between the facing electrode and the pixel defining layer.

12. The organic light emitting display apparatus of claim 11 , wherein the reflection member comprises a material that reflects light proceeding towards the reflection member from outside of the organic light emitting display apparatus.

13. The organic light emitting display apparatus of claim 12 , wherein the reflection member comprises a metal that reflects light proceeding towards the reflection member from outside of the organic light emitting display apparatus.

14. The organic light emitting display apparatus of claim 13 , wherein the reflection member comprises Al.

15. The organic light emitting display apparatus of claim 14 , wherein the reflection member has a thickness of 250 .ANG. or more.

16. The organic light emitting display apparatus of claim 11 , wherein the pixel electrode is a reflective electrode and the facing electrode is a transparent electrode.

17. The organic light emitting display apparatus of claim 1 , further comprising:

a plurality of reflection members;

an absorption layer on each of the reflection members; and

a sealing member that seals the organic light emitting unit,

wherein each of the reflection members is on a surface of the sealing member facing the substrate, and

wherein each of the absorption layers is between the corresponding reflection member and the substrate.

18. The organic light emitting display apparatus of claim 1 , wherein the light absorption layer is offset from a light emitting region of the organic light emitting unit in a direction parallel to the substrate.

19. The organic light emitting display apparatus of claim 1 , wherein the light absorption layer comprises a black matrix.

20. An organic light emitting display apparatus comprising:

a substrate;

an organic light emitting unit on the substrate;

a reflection member at a non-light emitting region of the organic light emitting unit; and

a light absorption layer covering an entire surface of the reflection member facing the organic light emitting unit.

21. The organic light emitting display apparatus of claim 1 , wherein the organic light emitting unit comprises:

a pixel electrode;

a facing electrode over the pixel electrode; and

an intermediate layer between the pixel electrode and the facing electrode, and

wherein the light absorption layer is electrically isolated from the facing electrode.
