Abstract

A display device includes a first substrate, a second substrate and a blocking member. The first substrate has a light emitting element. The second substrate faces the first substrate. The blocking member is arranged between the first and second substrates. The blocking member includes a first blocking layer and a second blocking layer.

Claims

1. A display device, comprising:

a first substrate comprising a light emitting element, the light emitting element including;

a first electrode;

a second electrode facing the first electrode; and

an organic light emitting layer arranged between the first electrode and the second electrode;

a second substrate facing the first substrate;

a blocking member that is arranged between the first substrate and the second substrate, the blocking member contacting the second electrode of the light emitting element and the second substrate to cover the light emitting element, and

a protection layer arranged between the blocking member and the light emitting element;

wherein the blocking member comprises;

a first blocking layer disposed between the second electrode and the protection layer, and

a second blocking layer disposed between the protection layer and the second substrate.

2. The display device of claim 1, wherein the second substrate comprises glass.

3. The display device of claim 1, wherein the second substrate is about 0.1 mm to about 10 mm thick.

4. The display device of claim 1, wherein the second substrate is about 1 mm to about 10 mm thick.

5. The display device of claim 1, wherein at least one of the first blocking layer and the second blocking layer comprises at least one of a thermosetting resin and a photocurable resin.

6. The display device of claim 1, wherein at least one of the first blocking layer and the second blocking layer comprises a desiccant material.

7. The display device of claim 1, wherein the second substrate comprises a receiving groove.

8. The display device of claim 1, wherein the second blocking layer of the blocking member contacts a portion of the first substrate and the first blocking layer of the blocking member.

9. A display device, comprising:

a first substrate comprising a light emitting element and a cover layer formed on the light emitting element;

a second substrate facing the first substrate;

a blocking member that is arranged between the first substrate and the second substrate, the blocking member contacting the cover layer and the second substrate to cover the light emitting element, and

further comprising a protection layer arranged between the blocking member and the light emitting element,

wherein the blocking member comprises;

a first blocking layer disposed between the cover layer and the protection layer; and

a second blocking layer disposed between the protection layer and the second substrate.

10. The display device of claim 9, wherein the protection layer comprises an organic material.

11. The display device of claim 10, wherein the protection layer comprises a high polymer.

12. The display device of claim 9, wherein the protection layer comprises an inorganic material.

13. The display device of claim 9, wherein the protection layer comprises an organic layer and an inorganic layer alternately arranged with each other.

14. The display device of claim 9, wherein the protection layer comprises a desiccant material.

15. The display device of claim 9, wherein the protection layer comprises at least one material selected from the group consisting of calcium, barium, calcium oxide, and barium oxide.
