Abstract

An organic light-emitting display apparatus includes a first substrate including a display area and a peripheral area; a second substrate opposing the first substrate; an insulating layer disposed on the first substrate and including one or more openings; and a sealing member interconnecting the first substrate and the second substrate to each other and interposed between the first and second substrates. The one or more openings are disposed between a first conductive layer disposed on the display area and a second conductive layer disposed on the peripheral area. The one or more openings are at least partially or entirely filled with the sealing member.

First claim

What is claimed is:

1 . An organic light-emitting display apparatus comprising:
a first substrate comprising a display area and a peripheral area; a second substrate opposing the first substrate; an insulating layer disposed on the first substrate and comprising one or more openings; and a sealing member interconnecting the first substrate and the second substrate to each other and interposed the first substrate and the second substrate, wherein the one or more openings are disposed between a first conductive layer disposed on the display area and a second conductive layer disposed on the peripheral area, and the one or more openings are at least partly or entirely filled with the sealing member.

2 . The organic light-emitting display apparatus of claim 1 , wherein the first conductive layer is a power line disposed on the display area.

3 . The organic light-emitting display apparatus of claim 1 , wherein the sealing member contacts the first conductive layer.

4 . The organic light-emitting display apparatus of claim 1 , wherein the first conductive layer is disposed at a different layer level than the second conductive layer.

5 . The organic light-emitting display apparatus of claim 1 , wherein the first conductive layer is disposed above the insulating layer, and the second conductive layer is disposed under the insulating layer.

6 . The organic light-emitting display apparatus of claim 1 , wherein the first conductive layer and the second conductive layer are formed of different materials from each other.

7 . The organic light-emitting display apparatus of claim 1 , wherein at least one of the first conductive layer and the second conductive layer comprises metal.

8 . The organic light-emitting display apparatus of claim 1 , wherein the one or more openings extend along a lengthwise direction of the sealing member when viewed in a viewing direction perpendicular to a major surface of the first substrate.

9 . The organic light-emitting display apparatus of claim 1 , wherein the one or more openings comprise first and second openings separate in a lengthwise direction of the sealing member when viewed in a viewing direction perpendicular to a major surface of the first substrate.

10 . The organic light-emitting display apparatus of claim 9 , wherein a distance between the first and second openings is less than a maximum width of each of the first and second openings.

11 . The organic light-emitting display apparatus of claim 1 , wherein the one or more openings are formed in one of a polygonal shape, a circular shape, and an oval shape.

12 . The organic light-emitting display apparatus of claim 1 , further comprising a transistor formed on the display area, wherein the first conductive layer comprises a material that is the same as a material forming at least one of a source electrode and a drain electrode of the transistor.

13 . The organic light-emitting display apparatus of claim 12 , wherein the second conductive layer comprises a material that is the same as a material forming a gate electrode of the transistor.

14 . The organic light-emitting display apparatus of claim 1 , wherein a material that is the same as a material forming the first conductive layer is disposed in at least one of the one or more openings.

15 . The organic light-emitting display apparatus of claim 1 , wherein the sealing member has a first width measured at its lower surface facing the first substrate and a second width measured at its upper surface facing the second substrate, the first width being different from the second width.

16 . The organic light-emitting display apparatus of claim 15 , wherein the first width is less than the second width.

17 . The organic light-emitting display apparatus of claim 1 , wherein the insulating layer comprises a material that is the same as a material forming an interlayer insulating layer formed on the display area.

18 . An organic light-emitting display apparatus comprising:
a first substrate comprising a display area and a peripheral area; a second substrate opposing the first substrate; an insulating layer disposed on the first substrate and comprising one or more openings; and a sealing member interconnecting the first substrate and the second substrate to each other and interposed between the first substrate and the second substrate, wherein at least one of the one or more openings is formed in a first conductive layer disposed on the display area, and the one or more openings are filled with the sealing member.

19 . The organic light-emitting display apparatus of claim 18 , wherein the first conductive layer is a power line of the display area.

20 . The organic light-emitting display apparatus of claim 18 , further comprising a second conductive layer disposed on the peripheral area,
wherein the first conductive layer and the second conductive layer overlap each other.
