Abstract

A display device includes pixel circuits disposed on a substrate, each of the pixel circuits comprising a transistor and a storage capacitor, display elements electrically connected to the pixel circuits, and a metal layer disposed between the substrate and the pixel circuits, the metal layer comprising through-holes, wherein the through-holes of the metal layer include a first through-hole, and a second through-hole disposed adjacent to the first through-hole.

First claim

What is claimed is:

1. A display device comprising:
pixel circuits disposed on a substrate, each of the pixel circuits comprising a transistor and a storage capacitor;
display elements respectively electrically connected to the pixel circuits; and
a metal layer disposed between the substrate and the pixel circuits, the metal layer comprising through-holes, wherein
the through-holes of the metal layer comprise:
a first through-hole; and
second through-hole spaced apart from the first through-hole, and

the second through-hole is entirely surrounded by the first through-hole in a plan view.

2. The display device of claim 1 , wherein the first through-hole or the second through-hole comprises an uneven side edge.

3. The display device of claim 1 , wherein
the metal layer comprises a first metal part entirely surrounding the second through-hole, and
the first metal part has an isolated shape.

4. The display device of claim 3 , wherein the first metal part overlaps at least one of the display elements.

5. The display device of claim 3 , wherein the first metal part overlaps at least one of the pixel circuits.

6. The display device of claim 3 , wherein
the metal layer further comprises a second metal part spaced apart from the first metal part, and
the second metal part has an isolated shape.

7. The display device of claim 6 , wherein the metal layer further comprises a third through-hole entirely surrounded by the second metal part.

8. The display device of claim 6 , wherein the metal layer further comprises a third through-hole entirely surrounded by the second metal part.

9. A display device comprising:
pixel circuits disposed on a substrate, each of the pixel circuits comprising a transistor and a storage capacitor;
display elements respectively electrically connected to the pixel circuits; and
a metal layer disposed between the substrate and the pixel circuits, the metal layer comprising through-holes, wherein the through-holes of the metal layer comprise a first through-hole having a mesh shape and metal parts separated from each other.

10. The display device of claim 9 , wherein the metal layer further comprises second through-holes respectively disposed in the metal parts.

11. The display device of claim 10 , wherein the first through-hole or the second through-hole comprises an uneven side edge.

12. The display device of claim 9 , wherein at least one of the metal parts overlaps at least one of the display elements.

13. The display device of claim 9 , wherein at least one of the metal parts overlaps at least one of the pixel circuits.

14. An electronic apparatus comprising:
a display device comprising at least one transmission area; and
a component disposed below the at least one transmission area, wherein
the display device comprises:
pixel circuits disposed on a substrate, each of the pixel circuits comprising a transistor and a storage capacitor;
display elements respectively electrically connected to the pixel circuits; and
a metal layer disposed between the substrate and the pixel circuits, the through-holes of the metal layer comprise:
a first through-hole; and
second through-hole spaced apart from the first through-hole, and

the second through-hole is entirely surrounded by the first through-hole in a plan view.

15. The display device of claim 14 , wherein the first through-hole or the second through-hole comprises an uneven side edge.

16. The display device of claim 14 , wherein
the metal layer comprises a first metal part entirely surrounding the second through-hole, and
the first metal part has an isolated shape.

17. The display device of claim 16 , wherein the first metal part overlaps at least one of the display elements.

18. The display device of claim 16 , wherein the first metal part overlaps at least one of the pixel circuits or at least one of the display elements.

19. The display device of claim 16 , wherein
the metal layer further comprises a second metal part spaced apart from the first metal part, and
the second metal part has an isolated shape.

20. The display device of claim 19 , wherein the metal layer further comprises a third through-hole entirely surrounded by the second metal part.
