Abstract

Provided are a display apparatus and a method of manufacturing the same. The display apparatus includes a display substrate arranged with a display portion including a display device; a sealing substrate disposed to face the display substrate; and a sealing portion that bonds the display substrate and the sealing substrate and surrounds the display portion. The sealing portion includes a first sealing portion that includes a sealing material and an insulating layer that includes at least one first opening; and a second sealing portion that is disposed outside the first sealing portion and includes at least one gas hole.

First claim

What is claimed is:

1. A display apparatus, comprising:
a display substrate arranged with a display portion including a display device;
a sealing substrate disposed to face the display substrate; and
a sealing portion that bonds the display substrate and the sealing substrate and surrounds the display portion, the sealing portion including:
a first sealing portion that includes a sealing material and an insulating layer that includes at least one first opening; and
a second sealing portion that is disposed outside the first sealing portion and includes at least one gas hole passing through the insulating layer, wherein the insulating layer is disposed over a lower insulating layer, and the first opening exposes the lower insulating layer.

2. A display apparatus, comprising:
a display substrate arranged with a display portion including a display device;
a sealing substrate disposed to face the display substrate; and
a sealing portion that bonds the display substrate and the sealing substrate and surrounds the display portion, the sealing portion including:
a first sealing portion that includes a sealing material and an insulating layer that includes at least one first opening; and
a second sealing portion that is disposed outside the first sealing portion and includes at least one gas hole, wherein the at least one first opening is connected to the at least one gas hole by a connection hole.

3. The display apparatus as claimed in claim 2 , wherein an area of the at least one gas hole is larger than an area of the at least one first opening.

4. The display apparatus as claimed in claim 2 , wherein:
the insulating layer includes a plurality of first insulating layer openings, and
each of the first insulating layer openings is connected to an adjacent first opening through a connection hole.

5. The display apparatus as claimed in claim 2 , wherein the first sealing portion further includes a metal pattern layer including at least one second opening.

6. The display apparatus as claimed in claim 5 , wherein the insulating layer includes a plurality of first openings that are formed inside the second opening.

7. The display apparatus as claimed in claim 5 , wherein:
the display portion includes a thin-film transistor including an active layer, a gate electrode, a source electrode, and a drain electrode, and
the metal pattern layer is formed of a same material and on a same layer as the gate electrode.

8. The display apparatus as claimed in claim 5 , wherein:
the display portion including a first thin-film transistor including a first active layer, a first gate electrode, a first source electrode, and a first drain electrode, and a second thin-film transistor including a second active layer, a second gate electrode, a second source electrode, and a second drain electrode,
a gate insulating film is disposed between the first gate electrode and the second gate electrode, and
the metal pattern layer includes a same material and a same layer as the first or second gate electrode.

9. The display apparatus as claimed in claim 2 , wherein the first sealing portion further includes:
a first metal pattern layer includes at least one second opening; and
a second metal pattern layer including a third opening on the first metal pattern layer.

10. The display apparatus e as claimed in claim 9 , wherein:
the display portion includes a first thin-film transistor including a first active layer, a first gate electrode, a first source electrode, and a first drain electrode, and a second thin-film transistor including a second active layer, a second gate electrode, a second source electrode, and a second drain electrode,
a gate insulating film is disposed between the first gate electrode and the second gate electrode,
the first metal pattern layer is formed of a same material and on a same layer as the first gate electrode, and
the second metal pattern layer is formed of a same material and on a same layer as the second gate electrode.

11. The display apparatus as claimed in claim 2 , wherein the sealing material is hardened by a laser.

12. The display apparatus as claimed in claim 2 , wherein an additional sealing material is disposed on the second sealing portion.

13. The display apparatus as claimed in claim 2 , wherein the sealing substrate overlaps the at least one gas hole.
