Abstract

A display panel may include a first hole, a second hole, a display element, a switching element, a wire, and a conductive member. The second hole may be spaced from the first hole. The switching element may be electrically connected to the display element. The wire may bypass the first hole in a plan view of the display panel and may be electrically connected to the switching element. The conductive member may surround each of the first hole and the second hole in the plan view of the display panel, may have an opening between the first hole and the second hole in the plan view of the display panel, and may partially cover the wire. An edge portion of the conductive member may intersect the wire and may be positioned between the display element and the first hole in the plan view of the display panel.

Claims (40)

1. A display panel comprising:

a first hole;

a second hole spaced from the first hole;

a display element;

a switching element electrically connected to the display element;

a first wire between the first hole and the second hole in a plan view of the display panel and electrically connected to the switching element; and

a conductive member having a first opening between the first hole and the second hole in the plan view of the display panel, and partially covering the first wire, wherein a first edge portion of the conductive member intersects the first wire and is positioned between the display element and the first hole in the plan view of the display panel.

2. The display panel of claim 1 , wherein the first wire is a data line electrically connected to the switching element for applying a data signal to the display element.

3. The display panel of claim 2 , wherein the first opening has a first width in a first direction and has a second width in a second direction, and wherein the first width is unequal to the second width.

4. The display panel of claim 3 , wherein the first opening has a first edge crossing the data line and including at least a curved portion.

5. The display panel of claim 1 , wherein the conductive member comprises holes spaced from one another, and wherein

each of the holes is smaller than the first opening in the plan view of the display panel.

6. The display panel of claim 1 , wherein the conductive member comprises holes spaced from one another, and wherein at least one of the holes partially exposes the first wire.

7. The display panel of claim 1 , further comprising a second wire bypassing an edge of the first hole, wherein the first opening is spaced from the second wire in the plan view of the display panel.

8. The display panel of claim 1 , further comprising:

an initialization voltage line electrically connected to the conductive member and configured to provide a constant voltage to the conductive member.

9. The display panel of claim 1 , wherein the conductive member has a constant voltage.

10. The display panel of claim 1 , wherein the display element comprises a pixel electrode, an opposite electrode, and an emission layer between the pixel electrode and the opposite electrode.

11. The display panel of claim 10 , wherein a material of the conductive member is identical to a material of the pixel electrode.

12. The display panel of claim 1 , wherein the conductive member comprises a third hole and a fourth hole respectively corresponding to the first hole and the second hole.

13. A display panel comprising:

a substrate comprising a first area and a second area, a non-display area surrounding the first and second areas, and a display area surrounding the non-display area;

a plurality of display elements arranged in the display area and each comprising a pixel electrode, an opposite electrode, and an emission layer between the pixel electrode and the opposite electrode;

a plurality of wires bypassing at least a portion of an edge of each of the first and second areas in the non-display area; and

an electrode layer covering at least one of the plurality of wires in the non-display area and having an opening that is positioned between the first area and the second area.

14. The display panel of claim 13 , wherein the plurality of wires comprise a plurality of data lines applying a data signal to a plurality of pixel circuits that are electrically respectively coupled to the plurality of display elements,

the plurality of data lines comprise a first data line and a second data line to correspond to the at least one opening, and

a size of an area of the first data line overlapping the electrode layer is different from a size of an area of the second data line overlapping the electrode layer.

15. The display panel of claim 13 , wherein the electrode layer comprises a plurality of holes apart from one another, and

at least one of the plurality of holes arranged to surround the first and second areas.

16. The display panel of claim 13 , wherein the plurality of wires comprise a plurality of data lines applying a data signal to a plurality of pixel circuits that are electrically respectively coupled to the plurality of display elements, and

a plurality of initialization voltage lines electrically connected to the electrode layer.

17. The display panel of claim 16 , wherein the plurality of initialization voltage lines have a constant voltage, and

the electrode layer has a same level of voltage as the plurality of initialization voltage lines.

18. The display panel of claim 13 , wherein the electrode layer comprises a same material as the pixel electrode.

19. The display panel of claim 13 , further comprising an organic insulating layer below the electrode layer,

wherein the electrode layer exposes at least a portion of the organic insulating layer through the at least one opening.

20. The display panel of claim 13 , further comprising:

at least one groove provided in the non-display area and more adjacent to the first and second areas than the plurality of wires; and

an encapsulation layer covering the plurality of display elements and comprising an inorganic encapsulation layer and an organic encapsulation layer.
