Abstract

A display device includes: an insulating substrate, where a through hole is defined through the insulating substrate; and an organic layer which covers the insulating substrate. In the display device, a barrier area surrounding the through hole is defined in the insulating substrate, and an interruption portion, at which the organic layer is interrupted, is defined in the barrier area.

Claims (37)

1. A display device comprising:

an insulating substrate comprising an active area, a through hole defined through the insulating substrate, a barrier area surrounding the through hole, and a dam area between the barrier area and the active area, comprising a first substrate, and a second substrate disposed on the first substrate;

a first layer disposed between the first substrate and the second substrate;

a second layer disposed on the second substrate;

a semiconductor layer on the second layer; and

an organic layer disposed on the second layer,

wherein the barrier area comprises a plurality of grooves at least partially recessed from a surface of the second substrate, and

wherein the organic layer is interrupted by the plurality of grooves.

2. The display device of claim 1 , further comprising:

a gate insulating layer on the semiconductor layer,

a gate electrode on the gate insulating layer,

an interlayer insulating layer on the gate electrode, and

a source electrode and a drain electrode on the interlayer insulating layer,

wherein the source electrode and the drain electrode each connect to the semiconductor layer.

3. The display device of claim 2 , further comprising:

a first electrode disposed on the drain electrode, and

a second electrode disposed on the first electrode,

wherein the first electrode is connected to the drain electrode,

wherein the organic layer disposed between the first electrode and the second electrode in the active area.

4. The display device of claim 1 ,

wherein a first area is defined between the grooves.

5. The display device of claim 4 , wherein the organic layer is disposed in each of the grooves.

6. The display device of claim 5 ,

wherein the organic layer is disposed on the first area, and

wherein the organic layer disposed on the first area is coupled to the organic layer disposed in one of the grooves which is adjacent to the first area, and is not coupled to the organic layer disposed in the other one of the grooves which adjacent to the first area.

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

an encapsulation film disposed on the second electrode, wherein the encapsulation film comprises a first inorganic film, a first organic film disposed on the first inorganic film, and a second inorganic film disposed on the first inorganic film.

8. The display device of claim 7 , further comprising:

a dam disposed in the dam area,

wherein the dam does not overlap the first organic film, and the dam overlaps the first inorganic film and the second inorganic film.

9. The display device of claim 8 , wherein the first inorganic film and the second inorganic film directly contact each other on the dam.

10. The display device of claim 1 , wherein the plurality of grooves penetrate the second substrate in the thickness direction and the first layer is exposed in the plurality of grooves,.

11. The display device of claim 1 , wherein each of the first substrate and the second substrate includes at least one of polyimide, polyethylene terephthalate, polycarbonate, polyethylene napthalate, polyarylate, and polyetherimide.

12. The display device of claim 1 , wherein each of the first layer and the second layer includes at least one of silicon oxide, silicon nitride and silicon oxynitride.

13. The display device of claim 1 , wherein the through hole has a quadrilateral shape.

14. The display device of claim 1 , wherein the dam has a quadrilateral shape in a plan view.

15. The display device of claim 1 , wherein the dam has a circular shape in a plan view.
