Abstract

A display panel includes: a first substrate including an opening area, a display area, and a non-display area; a plurality of display elements arranged in the display area; a second substrate facing the first substrate with the plurality of display elements therebetween; a sealing member arranged between the first substrate and the second substrate; a first conductive line between the opening area and the display area, the first conductive line being located in the non-display area; a second conductive line located in the non-display area; and at least one insulating layer arranged between the first conductive line and the second conductive line.

Claims (53)

1. A display panel comprising:

a first substrate comprising an opening area, a display area, and a non-display area;

a plurality of display elements arranged in the display area;

a second substrate facing the first substrate with the plurality of display elements therebetween;

a sealing member interposed between the first substrate and the second substrate and located in the non-display area;

a first conductive line between the opening area and the display area, the first conductive line being located in the non-display area;

a second conductive line located in the non-display area; and

at least one insulating layer interposed between the first conductive line and the second conductive line,

wherein the first conductive line and the second conductive line comprise different metals, and the first conductive line is less in thermal conductivity than the second conductive line.

2. The display panel of claim 1 , wherein

the first conductive line is interposed between the first substrate and a first portion of the sealing member, and the second conductive line is interposed between the first substrate and a second portion of the sealing member.

3. The display panel of claim 2 , wherein

an end portion of the first conductive line and an end portion of the second conductive line overlap each other.

4. The display panel of claim 3 , wherein

an end portion of the first conductive line and an end portion of the second conductive line are connected to each other through a contact hole defined in the at least one insulating layer.

5. The display panel of claim 2 , wherein

the first conductive line and the second conductive line are apart from each other.

6. The display panel of claim 5 , wherein

the first portion of the sealing member entirely surrounds the opening area, and the second portion of the sealing member is apart from the first portion and entirely surrounds the display area.

7. The display panel of claim 1 , wherein

each of the plurality of display elements comprises a pixel electrode, an intermediate layer, and an opposite electrode that are sequentially stacked, and

the second conductive line is electrically connected to the opposite electrode.

8. The display panel of claim 1 , wherein

the first conductive line comprises a plurality of sub-lines.

9. The display panel of claim 8 , wherein

the first conductive line further comprises a bridge line connecting the plurality of sub-lines.

10. A display panel comprising:

a first substrate and a second substrate facing each other with a plurality of display elements therebetween;

a sealing member between the first substrate and the second substrate;

at least one insulating layer interposed between the first substrate and the sealing member;

a first conductive line below a first portion of the sealing member;

a second conductive line below a second portion of the sealing member; and

a thin film transistor and a storage capacitor, the thin film transistor and the storage capacitor being electrically connected to a respective one of the plurality of display elements,

wherein the first conductive line and the second conductive line comprise different materials,

wherein the first conductive line comprises the same material as a material of a pixel electrode of the plurality of display elements, a gate electrode of the thin film transistor, and/or an electrode of the storage capacitor, and

the first conductive line is less in thermal conductivity than the second conductive line.

11. The display panel of claim 10 , wherein

one of the first conductive line and the second conductive line is located below the at least one insulating layer, and the other of the first conductive line and the second conductive line is located over the at least one insulating layer.

12. The display panel of claim 11 , wherein

an end portion of the first conductive line and an end portion of the second conductive line overlap each other.

13. The display panel of claim 12 , wherein

an end of the first conductive line and an end of the second conductive line are connected to each other through a contact hole defined in the at least one insulating layer.

14. The display panel of claim 10 , wherein

the second conductive line comprises a power supply line providing a voltage to the plurality of display elements.

15. The display panel of claim 10 , wherein

the first conductive line comprises a plurality of sub-lines and a bridge line connecting the plurality of sub-lines.

16. The display panel of claim 10 , wherein

the first substrate and the second substrate each comprise a display area and an opening area, and

the first conductive line is located between the display area and the opening area.

17. The display panel of claim 16 , wherein

the first conductive line and the second conductive line partially overlap each other.

18. The display panel of claim 16 , wherein

the first conductive line and the second conductive line are separated from each other.
