Abstract

In light emitting panel, the light emitting panel includes a substrate, a pixel part and a protection part. The pixel part has more than or equal to two unit parts separated from each other. The protection has a concave part marking off neighboring unit parts.

Claims

1. A light emitting panel comprising:

a substrate;

pixel parts located apart from each other, formed on the substrate; and

a protection part comprising an indented part,

wherein the indented part is concaved toward the substrate.

2. The light emitting panel of claim 1, wherein the indented part indicates a region between the pixel parts.

3. The light emitting panel of claim 1, wherein the indented part is separated from the substrate.

4. The light emitting panel of claim 1, further comprising:

a heat transmission part disposed at a location opposing to the indented part of the protection part on the substrate.

5. The light emitting panel of claim 4, wherein the heat transmission part is in contact with the indented part of the protection part.

6. The light emitting panel of claim 4, wherein the heat transmission comprises a Thermal pad.

7. The light emitting panel of claim 6, wherein the heat transmission part comprises a getter.

8. The light emitting panel of claim 1, wherein the protection part comprises either a metal, a glass or a plastic.

9. The light emitting panel of claim 1, wherein the pixel section emits a white color.

10. The light emitting panel of claim 9, wherein the pixel section comprises a sub-pixel.

11. The light emitting panel of claim 10, the sub-pixel comprises an emission part comprising an organic material disposed between two electrodes.

12. A light source comprising:

a substrate;

pixel parts divided from each other, formed on the substrate; and

a protection part comprising an indented part, wherein the indented part is concaved toward the substrate.

13. The light source of claim 12, wherein the indented part indicates a region between the pixel parts.

14. The light source of claim 12, wherein the indented part is separated from the substrate.

15. The light source of claim 12, further comprising:

a heat transmission part disposed at a location opposing to the indented part of the protection part on the substrate.

16. The light source of claim 15, wherein the heat transmission part is in contact with the indented part of the protection part.

17. The light source of claim 15, wherein the heat transmission comprises a Thermal pad.

18. The light source of claim 17, wherein the heat transmission part comprises a getter.

19. The light source of claim 12, wherein the protection part comprises either a metal, a glass or a plastic.

20. The light source of claim 12, wherein the pixel section emits a white color.

21. The light source of claim 20, wherein the pixel section comprises a sub-pixel.

22. The light source of claim 21, the sub-pixel comprises an emission part comprising an organic material disposed between two electrodes.

23. The light source of claim 20, the light source is used for a light apparatus or a back light unit.
