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 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
a second through-hole disposed adjacent to the first through-hole, wherein
the first through-hole and the second through-hole are different from each other in terms of at least one of shape, pattern, size, and width,
the through-holes of the metal layer further comprise an additional first through-hole adjacent to the first through-hole in a first direction, and
the second through-hole is disposed between the additional first through-hole and the first through-hole.

2. The display device of claim 1 , wherein
the metal layer comprises a metal part between the first through-hole and the second through-hole, and
the metal part overlaps the pixel circuits and the display elements.

3. The display device of claim 1 , wherein at least one of the first through-hole and the second through-hole comprises corner parts disposed in different directions from a center.

4. The display device of claim 3 , wherein at least one of the first through-hole and the second through-hole comprises a side edge between adjacent corner parts, and the side edge is curved.

5. The display device of claim 4 , wherein the side edge comprises an uneven part.

6. The display device of claim 3 , wherein
the first through-hole comprises four corner parts disposed in four different directions from a first center,
the second through-hole comprises four corner parts disposed in four different directions from a second center, and
one or more corner parts of the first through-hole and one or more corner parts of the second through-hole are adjacent to each other.

7. The display device of claim 1 , wherein the first through-hole entirely surrounds the second through-hole.

8. The display device of claim 1 , wherein at least one of the first through-hole and the second through-hole comprises a protruding portion.

9. The display device of claim 1 , wherein the metal layer further comprises a fine hole disposed between the first through-hole and the second through-hole.

10. 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 electrically connected to the pixel circuits; and
a metal layer disposed between the substrate and the pixel circuits, the metal layer comprising two adjacent first through-holes and a second through-hole between the two adjacent first through-holes,
wherein each of the two adjacent first through-holes is different from the second through-hole in terms of at least one of shape, pattern, size, and width.

11. The electronic apparatus of claim 10 , wherein
the metal layer comprises a metal part between at least one of the two adjacent first through-holes and the second through-hole, and
the metal part overlaps the pixel circuits and the display elements.

12. The electronic apparatus of claim 11 , wherein the metal part comprises a fine hole.

13. The electronic apparatus of claim 10 , wherein an edge of at least one of the two adjacent first through-holes and the second through-hole comprises an uneven part.

14. The electronic apparatus of claim 10 , wherein
at least one of the two-adjacent first through-holes and the second through-hole comprises four corner parts disposed in four different directions from a center, and
a curved side edge is between two neighboring corner parts of the four corner parts.

15. The electronic apparatus of claim 14 , wherein at least one of the two-adjacent first through-holes and the second through-hole comprises a fine concave portion or a fine protruding portion.

16. The electronic apparatus of claim 14 , wherein
each of the two-adjacent first through-holes and the second through-hole comprises four corner parts, and
at least one of the two-adjacent first through-holes and the second through-hole are arranged such that at least one of the corner parts of at least one of the two-adjacent first through-holes and at least one of the corner parts of the second through-hole are adjacent to each other.

17. The electronic apparatus of claim 10 , wherein at least one of the adjacent first through-holes entirely surrounds the second through-hole.

18. The electronic apparatus of claim 10 , wherein a width of at least one of the adjacent first through-holes is about 200 μm to about 300 μm.

19. The electronic apparatus of claim 10 , wherein the component comprises at least one of a sensor and a camera.
