Abstract

A display panel including: a first substrate; a second substrate opposing the first substrate; a sealing substructure on the first substrate, the sealing substructure surrounding a display unit having a plurality of pixels, the sealing substructure including a metal mesh layer having a mesh shape; and a sealing member between the sealing substructure and the second substrate to seal between the first substrate and the second substrate.

Claims

1. A display device comprising:

a first substrate having a display unit;

a second substrate opposing the first substrate;

a first insulation layer disposed on the first substrate;

a first metal layer disposed on the first insulation layer at a sealing portion and having a mesh shape in a top view;

a second insulation layer disposed on the first metal layer; and

a sealing member disposed between the second insulation layer and the second substrate in a cross-sectional view and surrounding the display unit having a plurality of pixels,

wherein the first metal layer includes a same material as a gate electrode in the display unit, and

wherein a top surface of the first metal layer physically does not contact to the sealing member.

2. The display device of claim 1, wherein the first insulation layer has the mesh shape.

3. The display device of claim 2, wherein the first metal layer includes a plurality of penetrating holes, and

wherein the first insulation layer includes a plurality of first holes each overlapping one of the penetrating holes.

4. The display device of claim 1, wherein the second insulation layer has the mesh shape.

5. The display device of claim 4, wherein the first metal layer includes a plurality of penetrating holes, and

wherein the second insulation layer includes a plurality of second holes each overlapping one of the penetrating holes.

6. A display device comprising:

a first substrate;

a second substrate opposing the first substrate;

a first insulation layer on the first substrate;

a metal mesh layer including a plurality of penetrating holes, the metal mesh layer on the first insulation layer; and

a sealing member disposed between the metal mesh layer and the second substrate and surrounding a display unit having a plurality of pixels,

wherein the first insulation layer includes a plurality of first holes each overlapping one of the penetrating holes.

7. The display device of claim 6, wherein the metal mesh layer includes a same material as a gate electrode in the display unit.

8. The display device of claim 6, wherein the first insulation layer includes a same material as a gate insulation layer in the display unit.

9. The display device of claim 6, further comprising:

a second insulation layer on the metal mesh layer.

10. The display device of claim 9, wherein the second insulation layer lodes a plurality of second holes each overlapping one of the penetrating holes.

11. The display device of claim 9, wherein the second insulation layer includes same material as an inter-layer dielectric insulating a gate electrode from a me electrode or a drain electrode in the display unit.

12. The display device of claim 9, wherein at least one of the first insulation layer, the metal mesh layer, or the second insulation layer has a step difference.

13. The display device of claim 9, further comprising:

a second metal layer on the second insulation layer.

14. The display device of claim 13, wherein at least a portion of the second metal layer is connected to the metal mesh layer.

15. The display device claim 13, wherein the second metal layer includes a same material as at least one of a source electrode or a drain electrode in the display unit.

16. The display device of claim 13, wherein the second metal layer includes a same material as at least one of an anode electrode or a cathode electrode in the display unit.

17. A display device comprising:

first substrate;

a second substrate opposing the first substrate;

a first insulation layer on the first substrate;

a metal mesh layer on the first insulation layer and having a mesh shape in a top view;

a second insulation layer on the metal mesh layer; and

a sealing member disposed between the second insulation layer and the second substrate in a cross-sectional view and surrounding a display unit having a plurality of pixels,

wherein at least one of the first insulation layer or the second insulation layer has the mesh shape.

18. The display device of claim 17, wherein the metal mesh layer includes a same material as a gate electrode in the display unit.

19. The display device of claim 17, wherein the first insulation layer includes a same material as a gate insulation layer in the display unit.

20. The display device of claim 17, wherein the second insulation layer includes a same material as an inter-layer dielectric insulating a gate electrode from a source electrode or a drain electrode in the display unit.
