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 (29)

1. A display device comprising:

a first substrate;

a second substrate disposed on the first substrate;

a through hole which is defined through the first substrate and the second substrate; and

a plurality of grooves disposed around the through hole,

wherein the plurality of grooves are defined in the second substrate.

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

an organic layer which covers the second substrate,

wherein the organic layer is disposed within the plurality of grooves.

3. The display device of claim 2 , wherein the organic layer comprises an organic light emitting layer.

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

a first electrode, and a second electrode opposite to the first electrode, and

the organic layer is disposed between the first electrode and the second electrode.

5. The display device of claim 4 , 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.

6. The display device of claim 5 , further comprising:

a dam located on the outside of the through hole, and the plurality of grooves,

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

7. The display device of claim 6 , the first inorganic film and the second inorganic film directly contact each other on the dam.

8. The display device of claim 1 , wherein the plurality of grooves are have the same planar shape.

9. The display device of claim 8 , wherein the planar shape of the plurality of grooves is a ring shape surrounding the through hole.

10. The display device of claim 1 , wherein

each of the plurality of grooves comprise a first sidewall and a second sidewall spaced apart from each other.

11. The display device of claim 10 , wherein a slope of the first sidewall and a slope of the second sidewall are substantially the same as each other.

12. The display device of claim 1 , wherein

a display area, which displays an image, and a non-display area, which is disposed outside the display area, are defined in the first substrate, and the second substrate, and

the through hole is defined in the display area.

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

an inorganic layer disposed between the first substrate and the second substrate.
