Abstract

Provided is an organic light emitting display device sealed maintaining durability by preventing permeation of oxygen and moisture and improving impact resistance. The light emitting display device includes a first substrate; a second substrate disposed facing toward the first substrate; an emission unit disposed between the first substrate and the second substrate and comprising a plurality of light emitting devices; a first sealant disposed between the first substrate and the second substrate, and surrounding the emission unit and combining the first substrate and the second substrate; a first region formed between around a flat portion of the first sealant and a margin of the second substrate; a second region formed between around a corner of the first sealant and a margin of the second substrate; a second sealant disposed in the first region; and a third sealant disposed in the second region.

Claims (26)

1. A light emitting display device, comprising:

a first substrate;

a second substrate disposed facing toward the first substrate;

an emission unit disposed between the first substrate and the second substrate, and the emission unit comprising a plurality of light emitting devices;

a first sealant disposed between the first substrate and the second substrate, and the first sealant surrounding the emission unit and combining the first substrate and the second substrate;

a first region formed between a flat portion of the first sealant and an outer edge of the second substrate;

a second region formed between a corner of the first sealant and the outer edge of the second substrate;

a second sealant disposed in the first region; and

a third sealant disposed in the second region.

2. The light emitting display device of claim 1 , wherein the first sealant comprises an inorganic material.

3. The light emitting display device of claim 2 , wherein the inorganic material comprises glass frit.

4. The light emitting display device of claim 1 , wherein one of the second sealant or the third sealant contacts the first substrate and the second substrate.

5. The light emitting display device of claim 1 , wherein one of the second sealant or the third sealant comprises an organic material.

6. The light emitting display device of claim 1 , wherein one of the second sealant or the third sealant contacts the first sealant.

7. The light emitting display device of claim 1 , wherein the second sealant and the third sealant are connected to each other.

8. The light emitting display device of claim 1 , wherein at least one insulating layer is interposed between the first, second, and third sealants and one of the first substrate and the second substrate.

9. A light emitting display device, comprising:

a first substrate;

a second substrate disposed facing toward the first substrate;

an emission unit disposed between the first substrate and the second substrate, and the emission unit comprising a plurality of light emitting devices;

a first sealant disposed between the first substrate and the second substrate, the first sealant surrounding the emission unit, and the first sealant combining the first substrate and the second substrate, with the first sealant being formed of an inorganic material;

a second sealant disposed around the first sealant and between the first substrate and the second substrate, combining the first substrate and the second substrate, being formed of an organic material, and having a first width; and

a third sealant disposed around the first sealant and between the first substrate and the second substrate, combining the first substrate and the second substrate, being formed of an organic material, and having a second width which is different from the first width.

10. The light emitting display device of claim 9 , wherein the third sealant is disposed to correspond to a corner of the second substrate.

11. The light emitting display device of claim 9 , wherein the second sealant and the third sealant contact the first sealant.

12. The light emitting display device of claim 9 , wherein at least one insulating layer is interposed between the first, second, and third sealant and the first substrate or the second substrate.
