Abstract

A display device includes a display device including a substrate, and a display unit disposed on the substrate. An encapsulating unit encapsulates the display unit. The encapsulating unit includes a barrier organic layer. The barrier organic layer includes a plurality of organic materials and a plurality of inorganic materials. The inorganic materials are arranged in free volumes between the organic materials.

Claims (32)

1. A display device comprising:

a substrate;

an encapsulating substrate facing the substrate;

a display unit between the substrate and the encapsulating substrate; and

an encapsulating material disposed between the substrate and the encapsulating substrate, and disposed around the display unit,

wherein the encapsulating material comprises a barrier organic layer,

wherein the barrier organic layer comprises an organic material and an inorganic material, and wherein the inorganic material is arranged in free volumes of the organic material,

wherein the encapsulating material is disposed apart from the display unit.

2. The display device of claim 1 , wherein the encapsulating material surrounds a circumference of the display unit.

3. The display device of claim 1 , wherein the encapsulating material contacts the substrate and the encapsulating substrate.

4. The display device of claim 1 , wherein the display unit comprises an organic light-emitting diode (OLED) and a thin-film transistor (TFT).

5. The display device of claim 1 , wherein the inorganic material comprises aluminum oxide.

6. The display device of claim 1 , wherein the barrier organic layer includes one or more of PET, polyimide, PC, epoxy, polyethylene, and PAR.

7. The display device of claim 1 , wherein the barrier organic layer comprises a non-slippery surface.

8. The display device of claim 1 , wherein the encapsulating substrate is flat, and the encapsulating material contacts the substrate at a first surface and the encapsulating substrate at a second surface opposite to the first surface.

9. The display device of claim 8 , wherein an inorganic layer is disposed on the barrier organic layer.

10. The display device of claim 9 , wherein a lower surface of the inorganic layer directly contacts the display unit, and wherein an upper surface of the inorganic layer directly contacts the barrier organic layer.

11. The display device of claim 8 , wherein the barrier organic layer has a larger solid volume relative to a solid volume of the inorganic layer.

12. The display device of claim 3 , wherein the barrier organic layer directly contacts the substrate at an upper surface and directly contacts the encapsulating substrate at a lower surface.

13. The display device of claim 3 , wherein the encapsulating material does not directly contact the display unit of the display device.

14. A display device comprising:

a substrate;

an encapsulating substrate facing the substrate;

a display unit disposed between the substrate and the encapsulating substrate; and

a first barrier organic layer contacting the substrate at a first surface and the encapsulating substrate at a second surface opposite to the first surface, wherein the first barrier organic layer at least partially surrounds the display unit without making contact therewith; and

a second barrier organic layer disposed on a surface of the display unit,

wherein the first and second barrier organic layers both comprise an organic material and an inorganic material, and

wherein the inorganic material is arranged in free volumes of the organic material.

15. The display device of claim 14 , wherein the inorganic material is continuously arranged in free volumes extending from a lower surface of the barrier organic layer to an upper surface of the barrier organic layer.

16. The display device of claim 14 , wherein the first and second barrier organic layers are spaced apart from one another.

17. The display device of claim 14 , wherein the barrier organic layer has at least one side that includes a rough texture.

18. The display device of claim 8 , wherein the barrier organic layer and the inorganic layer are alternately disposed.
