Abstract

A display apparatus includes a substrate including a transmission area, a display area, and a first non-display area between the transmission area and the display area, a display layer including display elements and bypass lines, an encapsulation member that covers the display elements and the bypass lines, a metal layer on the encapsulation member, and including a first hole corresponding to the transmission area, and an optical functional section including a second hole corresponding to the transmission area, wherein a first perpendicular distance from a center line, which passes through a center of the transmission area and is perpendicular to an upper surface of the substrate, to an edge of the first hole may be less than a second perpendicular distance from the center line to an edge of the second hole.

First claim

What is claimed is:

1. A display apparatus comprising:
a substrate including a transmission area,
a display area surrounding the transmission area, and
a first non-display area between the transmission area and the display area;
a display layer including display elements in the display area and bypass lines in the first non-display area;
an encapsulation member that covers the display elements and the bypass lines;
a metal layer on the encapsulation member, overlapping the bypass lines, and including a first hole corresponding to the transmission area;
an optical functional section including a second hole corresponding to the transmission area and overlapping the first hole of the metal layer; and
an input sensing section on the encapsulation member and including sensing electrodes and trace lines electrically coupled to the sensing electrodes,
wherein the metal layer is in a same layer as the input sensing section.

2. The display apparatus of claim 1 , wherein the metal layer includes a same material as the trace lines.

3. The display apparatus of claim 1 , wherein the metal layer has a ring shape.

4. The display apparatus of claim 1 , wherein the input sensing section includes at least one conductive layer including the sensing electrodes or the trace lines and an insulating layer on the at least one conductive layer, and
wherein the insulating layer covers an edge of the metal layer defining the first hole.

5. The display apparatus of claim 1 , wherein the display layer includes a plurality of insulating layers,
at least one of the plurality of insulating layers includes a hole corresponding to the transmission area.

6. The display apparatus of claim 5 , wherein at least one of the plurality of insulating layers continuously surrounds the transmission area.

7. The display apparatus of claim 1 , wherein the display layer includes an opposite electrode provided in common to the display elements, the opposite electrode includes an electrode-hole corresponding to the transmission area.

8. The display apparatus of claim 1 , wherein the display layer includes a plurality of insulating layers and an opposite electrode, and
the plurality of insulating layers include a hole corresponding to the transmission area.

9. The display apparatus of claim 1 , further comprising a window over the optical functional section, and a transparent adhesive layer between the optical functional section and the window.

10. The display apparatus of claim 1 , wherein at least one of the substrate or the sealing member includes a glass material.

11. The display apparatus of claim 1 , further comprising a camera under the substrate, and overlapping the first hole.

12. A display panel comprising:
a substrate including a transmission area,
a display area surrounding the transmission area, and
a first non-display area between the transmission area and the display area;
a display layer including display elements in the display area and bypass lines in the first non-display area;
an encapsulation member that covers the display elements and the bypass lines;
a metal layer on the encapsulation member, overlapping the bypass lines, and including a first hole corresponding to the transmission area; and
an input sensing section on the encapsulation member and including sensing electrodes and trace lines electrically coupled to the sensing electrodes,
wherein the metal layer is in a same layer as the input sensing section.

13. The display panel of claim 12 , wherein the metal layer includes a same material as the trace lines.

14. The display panel of claim 12 , wherein the metal layer has a ring shape.

15. The display panel of claim 12 , wherein the input sensing section includes at least one conductive layer including the sensing electrodes or the trace lines and an insulating layer on the at least one conductive layer, and
wherein the insulating layer covers an edge of the metal layer defining the first hole.

16. The display panel of claim 12 , wherein the display layer includes a plurality of insulating layers,
at least one of the plurality of insulating layers includes a hole corresponding to the transmission area.

17. The display panel of claim 16 , wherein at least one of the plurality of insulating layers continuously surrounds the transmission area.

18. The display panel of claim 12 , wherein the display layer includes an opposite electrode provided in common to the display elements, the opposite electrode includes an electrode-hole corresponding to the transmission area.

19. The display panel of claim 12 , further comprising an optical functional section including a second hole corresponding to the transmission area and overlapping the first hole of the metal layer.

20. The display panel of claim 12 , wherein at least one of the substrate or the sealing member includes a glass material.
