a lower substrate comprising a display area and a peripheral area around the display area;
an insulating layer on the display area and the peripheral area of the lower substrate, wherein a plurality of penetration holes are formed in the insulating layer in the peripheral area;
a conductive layer between the lower substrate and the first-insulating layer, wherein a plurality of penetration openings are formed in the conductive layer;
an upper substrate on the lower substrate; and
a sealant in the plurality of penetration holes bonding the lower substrate to the upper substrate, wherein the insulating layer comprises a plurality of penetration hole sets that correspond to the plurality of penetration openings in the conductive layer, and each penetration hole set of the plurality of penetration hole sets comprises two or more penetration holes of the plurality of penetration holes within a respective penetration opening of the plurality of penetration openings.

2. The organic light-emitting display apparatus of claim 1 , further comprising an additional insulating layer between the lower substrate and the insulating layer.

3. The organic light-emitting display apparatus of claim 1 , wherein an area of a penetration hole set from among the plurality of penetration hole sets in the insulating layer is narrower than an area of a corresponding penetration opening from among the plurality of penetration openings in the conductive layer.

4. The organic light-emitting display apparatus of claim 1 , wherein an inner surface of each penetration opening of the plurality of penetration openings in the conductive layer is covered by the insulating layer, and does not contact the sealant.

5. The organic light-emitting display apparatus of claim 1 , wherein a distance between the penetration holes in each of the plurality of penetration hole sets in the first insulating layer is 2.5 μm or more.

6. The organic light-emitting display apparatus of claim 1 , wherein a distance between penetration openings of the plurality of penetration openings in the conductive layer is 20.5 μm or more.

7. The organic light-emitting display apparatus of claim 1 , wherein the display area comprises a thin film transistor comprising a gate electrode, and wherein the conductive layer comprises a same material as that of the gate electrode in the thin film transistor.

8. The organic light-emitting display apparatus of claim 7 , wherein the conductive layer and the gate electrode are disposed on a same layer.

9. The organic light-emitting display apparatus of claim 1 , wherein in a surface parallel to the lower substrate, a total area of the plurality of penetration holes in the first insulating layer is in a range of 9.8% and 16.5% of an area of the sealant.

10. The organic light-emitting display apparatus of claim 1 , wherein the display area comprises a buffer layer, a gate insulating film, an interlayer insulating film, and a protective film, and wherein the insulating layer is an extended portion of at least one of the interlayer insulating film and the protective film.

11. The organic light-emitting display apparatus of claim 1 , wherein the conductive layer is located in the peripheral area and has a width-change part in which a width of the conductive layer changes.

12. The organic light-emitting display apparatus of claim 11 , wherein the first insulating layer has a first portion and a second portion, the first portion contacting a layer beneath the conductive layer through the plurality of penetration openings of the conductive layer, the second portion contacting the layer beneath the conductive layer outside the conductive layer in a region of the width-change part of the conductive layer.

13. The organic light-emitting display apparatus of claim 1 , wherein the conductive layer is located in the peripheral area and a center of the conductive layer is relatively closer to the display area than a center of the sealant.

14. The organic light-emitting display apparatus of claim 13 , further comprising an additional plurality of penetration holes formed in the insulating layer where the insulating layer does not correspond to the conductive layer, wherein a number of penetration holes the additional plurality of penetration holes of the insulating layer per unit area is higher than a number of penetration holes of the plurality of penetration holes of the insulating layer per unit area.

15. The organic light-emitting display apparatus of claim 1 , further comprising a dummy semiconductor layer under the insulating layer or in the insulating layer, wherein the dummy semiconductor layer locates in the peripheral area, and has a plurality of penetration apertures corresponding to the plurality of penetration holes of the insulating layer, and wherein the sealant fills the plurality of penetration apertures and the plurality of penetration holes.

16. The organic light-emitting display apparatus of claim 15 , wherein the display area comprises a thin film transistor comprising a semiconductor layer, and wherein the dummy semiconductor layer comprises a same material as that of the semiconductor layer in the thin film transistor.
