Abstract

An organic light-emitting display and a method of manufacturing the same are provided. An organic light-emitting display includes: a substrate including a light-emission region and a non-light-emission region around the light-emission region; a display device on the light-emission region of the substrate; and an encapsulation member on the display device. The encapsulation member includes a light-shielding member including a first light-shielding layer and a second light-shielding layer, the first light-shielding layer being in a region corresponding to the non-light-emission region, and the second light-shielding layer being on the first light-shielding layer; and a color conversion member in a region corresponding to the light-emission region.

Claims (64)

1. A display comprising:

a substrate comprising a light-emission region and a non-light-emission region around the light-emission region;

a display device on the light-emission region of the substrate; and

an encapsulation member on the display device,

wherein the encapsulation member comprises:

a light-shielding member comprising a first light-shielding layer and a second light-shielding layer, the first light-shielding layer being in a region corresponding to the non-light-emission region, and the second light-shielding layer being on the first light-shielding layer; and

a color conversion member in a region corresponding to the light-emission region, and

wherein the second light-shielding layer is located outside an opening formed in the first light-shielding layer, the opening corresponding to the light-emission region.

2. The display of claim 1 , wherein the encapsulation member further comprises a first protection layer between the display device and the light-shielding member.

3. The display of claim 2 , wherein the first protection layer comprises an inorganic material.

4. A display comprising:

a substrate comprising a light-emission region and a non-light-emission region around the light-emission region;

a display device on the light-emission region of the substrate;

an encapsulation member on the display device;

a first liquid repellent pattern between the light-shielding member and the color conversion member; and

a second liquid repellent pattern on the second light-shielding layer,

wherein the encapsulation member comprises:

a light-shielding member comprising a first light-shielding layer and a second light-shielding layer, the first light-shielding layer being in a region corresponding to the non-light-emission region, and the second light-shielding layer being on the first light-shielding layer; and

a color conversion member in a region corresponding to the light-emission region.

5. The display of claim 4 , wherein

the first liquid repellent pattern comprises a hydrophilic material, and

the second liquid repellent pattern comprises a hydrophobic material.

6. The display of claim 1 , further comprising a second protection layer on the light-shielding member and the color conversion member.

7. The display of claim 6 , wherein the second protection layer comprises an inorganic material.

8. The display of claim 1 , wherein

a width of the first light-shielding layer is greater than a width of the second light-shielding layer, and

a thickness of the second light-shielding layer is greater than a thickness of the first light-shielding layer.

9. A display comprising:

a substrate;

a first electrode on the substrate;

a first insulating layer covering an edge of the first electrode;

an intermediate layer on the first electrode and comprising an emission layer;

a second electrode covering the intermediate layer and facing the first electrode;

a second insulating layer covering the second electrode;

a light-shielding member comprising a first light-shielding layer and a second light-shielding layer, the first light-shielding layer being on the second insulating layer and having a first opening through which a portion of the second insulating layer corresponding to the emission layer is exposed, and the second light-shielding layer being on the first light-shielding layer and having a second opening through which the first opening and an edge of the first light-shielding layer are exposed; and

a color conversion member within the first and second openings.

10. The display of claim 9 , further comprising:

a first liquid repellent pattern on respective lateral surfaces of the first and second openings; and

a second liquid repellent pattern on the second light-shielding layer.

11. The display of claim 10 , wherein

the first liquid repellent pattern comprises a hydrophilic material, and

the second liquid repellent pattern comprises a hydrophobic material.

12. The display of claim 9 , further comprising a third insulating layer on the light-shielding member and the color conversion member.

13. The display of claim 12 , wherein the third insulating layer comprises an inorganic material.

14. The display of claim 9 , wherein

a width of the first light-shielding layer is greater than a width of the second light-shielding layer, and

a thickness of the second light-shielding layer is greater than a thickness of the first light-shielding layer.

15. A method of manufacturing a display, the method comprising:

providing a substrate comprising a light-emission region and a non-light-emission region around the light-emission region;

forming a display device on the light-emission region of the substrate;

forming a light-shielding member on the display device, the light-shielding member comprising a first light-shielding layer and a second light-shielding layer, wherein the first light-shielding layer is in a region corresponding to the non-light-emission region, and the second light-shielding layer is on the first light-shielding layer; and

forming a color conversion member in a region corresponding to the light-emission region, wherein the color conversion member is formed on the first light-shielding layer,

wherein the second light-shielding layer is located outside an opening formed in the first light-shielding layer, the opening corresponding to the light-emission region.

16. The method of claim 15 , further comprising, after the forming of the light-shielding member:

forming a first liquid repellent pattern on respective lateral surfaces of the first and second light-shielding layers; and

forming a second liquid repellent pattern on the second light-shielding layer.

17. The method of claim 15 , wherein the forming of the light-shielding member comprises:

forming the first light-shielding layer on the display device, the first light-shielding layer comprising the opening through which a portion of the display device corresponding to the light-emission region is exposed; and

forming the second light-shielding layer outside the opening of the first light-shielding layer, the second light-shielding layer comprising another opening through which an edge of the first light-shielding layer is exposed.

18. The method of claim 15 , further comprising forming a second protection layer on the light-shielding member and the color conversion member.

19. The method of claim 15 , wherein

a width of the first light-shielding layer is greater than a width of the second light-shielding layer, and
