Display device and method of manufacturing the same
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.
1. A display device comprising:
an insulating substrate, wherein a through hole is defined through the insulating substrate; and
an organic layer which covers the insulating substrate,
wherein
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.
2. The display device of claim 1 , wherein
a groove is defined on the insulating substrate in the barrier area.
3. The display device of claim 2 , wherein
the groove comprises a first sidewall and a second sidewall spaced apart from each other, and
the interruption portion is defined by the first sidewall.
4. The display device of claim 3 , wherein a slope of the first sidewall and a slope of the second sidewall are substantially the same as each other.
5. The display device of claim 3 , further comprising:
an electrode which covers the organic layer,
wherein the electrode is interrupted at the interruption portion.
6. The display device of claim 5 , wherein the electrode contacts the first sidewall and does not contact the second sidewall.
7. The display device of claim 2 , wherein
a display area, which displays an image, and a non-display area, which is disposed outside the display area, are defined in the insulating substrate, and
the through hole is defined in the display area.
8. The display device of claim 2 , wherein
the insulating substrate comprises a first substrate, an inorganic layer and a second substrate, which are stacked sequentially one on another, and
the groove is defined in the second substrate.
9. The display device of claim 2 , wherein a planar shape of the groove is a ring shape surrounding the through hole.
10. The display device of claim 1 , wherein
a dam area surrounding the barrier area is defined in the insulating substrate outside the barrier area, and
a dam is disposed on the insulating substrate in the dam area.
11. The display device of claim 10 , wherein
the dam is provided in plural, and
the dams comprise a first dam, and a second dam spaced apart from the first dam.
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 insulating substrate, and
the through hole is defined in the display area.
13. The display device of claim 12 , wherein
the display area comprises 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.
14. The display device of claim 12 , wherein the organic layer comprises an organic light emitting layer.
15. 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 insulating substrate, and
the through hole is defined in the non-display area.
16. A method of manufacturing a display device, the method comprising:
providing a dam on a first area of an insulating substrate, wherein the insulating substrate is disposed on a carrier substrate, and the first area, a second area and a third area are defined in the insulating substrate;
forming a laser cutting portion by irradiating a laser beam to the third area in a first direction;
forming a groove in the insulating substrate by irradiating a laser beam to the second area in a second direction different from the first direction; and
providing an organic layer on the insulating substrate to at least partially cover the groove,
wherein an interruption portion, at which the organic layer is interrupted, is formed in the second area.
17. The method of claim 16 , further comprising:
detaching the carrier substrate from the insulating substrate; and
attaching a protective film to a lower surface of the insulating substrate.
18. The method of claim 17 , further comprising:
forming a through hole by cutting off a portion of the protective film corresponding to the third area.
19. The method of claim 16 , wherein
the groove comprises a first sidewall and a second sidewall, which are spaced apart from each other, and
the interruption portion is defined by the first sidewall.
20. The method of claim 16 , further comprising:
providing an electrode on the insulating substrate to cover the organic layer.
