Abstract

The present invention is to provide an organic light emitting display and a method of manufacturing the same, the light emitting display including: a first substrate on which a plurality of light emitting devices are formed; a second substrate disposed to face the first substrate; a dam member disposed between the first substrate and the second substrate to surround the plurality of light emitting devices; an inorganic sealing material disposed between the first substrate and the second substrate on an outward side of the dam member and attaching the first substrate and the second substrate; and a filling material provided between the first substrate and the second substrate on an inward side of the dam member and formed of at least one inert liquid selected from the group consisting of perfluorocarbon and fluorinert.

Claims (17)

1. A light emitting display comprising:

a first substrate on which a plurality of light emitting devices are formed;

a second substrate disposed to face the first substrate;

a dam member disposed between the first substrate and the second substrate to define an enclosed space to surround the plurality of light emitting devices, wherein a reflecting layer that reflects a laser or infrared rays is formed on a surface of the dam member;

an inorganic sealing material disposed between the first substrate and the second substrate on an outward side of the dam member and attaching the first substrate and the second substrate wherein the inorganic sealing member defines an enclosed space and is spaced from the dam member and wherein the inorganic material comprises fit; and

a filling material provided between the first substrate and the second substrate on an inward side of the dam member and formed of at least one inert liquid selected from the group consisting of perfluorocarbon and fluorinert.

2. The light emitting display as claimed in claim 1 , wherein the light emitting devices comprise first electrodes, organic light emitting layers and second electrodes.

3. The light emitting display as claimed in claim 2 , wherein the filling material is provided between the first substrate and the second substrate to be in contact with the second electrodes.

4. The light emitting display as claimed in claim 1 , wherein the dam member comprises an inorganic material.

5. The light emitting display as claimed in claim 1 , wherein the reflecting layer comprises at least one selected from the group consisting of Au, Ag, Pt, and Al.

6. The light emitting display as claimed in claim 1 , wherein the dam member comprises an organic material.

7. The light emitting display as claimed in claim 6 , wherein the organic material comprises at least one selected from the group consisting of epoxy, epoxy acrylate, bisphenol A type epoxy, cycloaliphatic epoxy resin, phenyl silicone resin or rubber, and acrylic epoxy resin.

8. The light emitting display as claimed in claim 6 , wherein the dam member is disposed to be separated from the inorganic sealing material.

9. The light emitting display as claimed in claim 6 , wherein the dam member and the inorganic sealing material are separated from each other by at least about 50 μm.

10. The light emitting display as claimed in claim 6 , wherein the inorganic sealing material comprises frit.

11. The light emitting display as claimed in claim 10 , wherein the frit is melted by a laser or infrared rays.

12. The light emitting display as claimed in claim 9 , wherein the frit comprises a transition metal compound.
