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 (36)

1. A display device comprising:

a substrate;

a display unit disposed on the substrate; and

an encapsulating unit encapsulating the display unit,

wherein the encapsulating unit comprises an inorganic layer disposed on the display unit, and a barrier organic layer disposed on the inorganic layer, wherein the inorganic layer comprises a first inorganic material,

wherein the barrier organic layer comprises an organic material and a second inorganic material,

wherein the second inorganic material is arranged in free volumes of the organic material, and

wherein the first inorganic material is different from the second inorganic material.

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

3. The display device of claim 1 , wherein the encapsulating unit comprises an encapsulating substrate and an encapsulating material, and wherein the barrier organic layer comprises the encapsulating material.

4. The display device of claim 1 , wherein the first inorganic material comprises one of silicon nitride, silicon oxide or silicon oxynitride, and wherein the second inorganic material comprises aluminum oxide.

5. A method of manufacturing a display device, the method comprising:

providing a substrate;

forming a display unit on the substrate; and

forming an encapsulating unit encapsulating the display unit,

wherein the forming the encapsulating unit comprises forming an inorganic layer directly on the display unit, and forming a barrier organic layer on the inorganic layer,

wherein the barrier organic layer comprises an organic material and an inorganic material,

wherein the inorganic material is arranged in free volumes of the organic material, and

wherein ends of the inorganic layer are in direct contact with the substrate.

6. The method of manufacturing the display device of claim 5 , wherein the forming the barrier organic layer comprises forming an organic layer and injecting an inorganic precursor into free volumes of the organic material forming the barrier organic layer.

7. The method of manufacturing the display device of claim 6 , wherein the forming the barrier organic layer further comprises adding a reactant to free volumes of the organic material after having injected the inorganic precursor into the free volumes of the organic material forming the barrier organic layer.

8. The method of manufacturing the display device of claim 7 , wherein the forming the barrier organic layer comprises converting the inorganic precursor to the inorganic material filling in the free volumes of the organic material forming the barrier organic layer by adding the reactant.

9. The method of manufacturing the display device of claim 5 , wherein a top surface of the barrier organic layer is rough.

10. The method of manufacturing the display device of claim 7 , wherein the inorganic precursor is trimethylaluminum (TMA, [(CH3)3Al]) and the reactant is H2O.

11. A display device comprising:

a substrate;

a display unit disposed on the substrate; and

an encapsulating unit encapsulating the display unit,

wherein the encapsulating unit comprises an inorganic layer in direct contact with upper and side portions of the display unit, and a barrier organic layer disposed on the inorganic layer,

wherein the barrier organic layer comprises a plurality of organic materials and a plurality of inorganic materials, and

wherein ends of the inorganic layer are in direct contact with the substrate.

12. The display device of claim 11 , wherein the plurality of organic materials include a polymer.

13. The display device of claim 11 , wherein the barrier organic layer includes one or more of PET, polyimide, PC, epoxy, polyethylene, and PAR.

14. The display device of claim 11 , wherein the barrier organic layer includes a polymerized monomer composition including a diacrylate monomer and a triacrylate monomer.

15. The display device of claim 11 , wherein the barrier organic layer includes a photoinitiator.

16. The display device of claim 11 , wherein the inorganic layer is one of silicon nitride, silicon oxide or silicon oxynitride, and wherein the second inorganic material comprises aluminum oxide.
