Abstract

Provided is a display apparatus, including a substrate; a plurality of pixels that are on the substrate and include at least one display device; a separation area that is on the substrate and between two adjacent pixels from among the plurality of pixels; and a penetrating portion that is in the separation area and penetrates the substrate.

Claims

1. A display apparatus, comprising:

a substrate;

a plurality of pixels that are on the substrate and include at least one display device;

a separation area that is on the substrate and between two adjacent pixels from among the plurality of pixels; and

a penetrating portion that is in the separation area and penetrates the substrate.

2. The display apparatus as claimed in claim 1, further comprising at least one wire electrically connected to the plurality of pixels, wherein the at least one wire does not overlap the penetrating portion.

3. The display apparatus as claimed in claim 2, wherein the at least one wire extends in one direction and includes an area that bends in a direction intersecting the one direction around the penetrating portion.

4. The display apparatus as claimed in claim 2, wherein:

the at least one wire includes a plurality of wires, and

two wires adjacent to each other in one direction from among the plurality of wires are symmetrical about the penetrating portion.

5. The display apparatus as claimed in claim 2, wherein:

the at least one wire includes a plurality of wires and the penetrating portion includes a plurality of penetrating portions,

the plurality of wires include a first wire, a second wire, and a third wire,

the first wire is electrically connected to pixels that are arranged in a first direction from among the plurality of pixels,

the second and third wires are each electrically connected to pixels arranged in a second direction crossing the first direction from among the plurality of pixels,

the second wire includes an area that bends in the first direction around one of the plurality of penetrating portions, and

the third wire includes an area that bends in the first direction around another one of the plurality of penetrating portions.

6. The display apparatus as claimed in claim 1, wherein:

the separation area includes a first separation area and a second separation area,

the first separation area includes an area between two pixels adjacent in a first direction from among the plurality of pixels,

the second separation area includes an area between two pixels adjacent in a second direction intersecting the first direction from among the plurality of pixels,

the penetrating portion includes a first penetrating portion and a second penetrating portion, and

the first penetrating portion is in the first separation area and the second penetrating portion is in the second separation area.

7. The display apparatus as claimed in claim 6, wherein the first penetrating portion passes by the first separation area and has an elongated shape corresponding to an area where an area obtained by extending the first separation area and an area obtained by extending the second separation area overlap each other.

8. The display apparatus as claimed in claim 6, wherein the first penetrating portion has an elongated shape corresponding to a space between the two pixels adjacent in the first direction and a space between the two pixels adjacent in the second direction.

9. The display apparatus as claimed in claim 6, wherein the second penetrating portion passes by the second separation area and has an elongated shape corresponding to an area where an area obtained by extending the second separation area and an area obtained by extending the first separation area overlap each other.

10. The display apparatus as claimed in claim 6, wherein the second penetrating portion has an elongated shape corresponding to a space between the two pixels adjacent in the second direction and a space between the two pixels adjacent in the first direction.

11. The display apparatus as claimed in claim 6, wherein the first penetrating portion and the second penetrating portion are spaced apart from each other.

12. The display apparatus as claimed in claim 6, wherein:

the penetrating portion includes a plurality of first penetrating portions and a plurality of second penetrating portions,

at least one of the plurality of second penetrating portions is between two adjacent first penetrating portions from among the plurality of first penetrating portions, and

at least one of the plurality of first penetrating portions is between two adjacent second penetrating portions from among the plurality of second penetrating portions.

13. The display apparatus as claimed in claim 1, further comprising a first insulating layer on the substrate, wherein the first insulating layer overlaps the penetrating portion.

14. The display apparatus as claimed in claim 1, further comprising a first insulating layer on the substrate, wherein the first insulating layer includes an insulating penetrating portion having an area overlapping the penetrating portion.

15. The display apparatus as claimed in claim 1, wherein:

the plurality of pixels each includes a plurality of sub-pixels,

sub-pixels of at least one pixel of the plurality of pixels are arranged in one direction, and

sub-pixels of a pixel adjacent to the at least one pixel are arranged in a direction crossing the one direction.

16. The display apparatus as claimed in claim 15, further comprising at least one wire electrically connected to each of the plurality of sub-pixels of each of the plurality of pixels, wherein:

the at least one wire does not overlap the penetrating portion, and

the at least one wire includes a plurality of connecting wires each connected to the plurality of sub-pixels of one of the plurality of pixels and spaced apart from each other, a common wire commonly connected to the plurality of connecting wires, and a body wire connected to the common wire and corresponding to a side of one of the plurality of sub-pixels.

17. The display apparatus as claimed in claim 1, wherein the substrate includes a flexible material.

18. The display apparatus as claimed in claim 17, wherein the flexible material contains an organic material.
