Abstract

A display apparatus is disclosed that includes a substrate, a partition wall, and wiring. The substrate includes a display area and a peripheral area. The partition wall is arranged in the peripheral area. The wiring is arranged over the substrate extends from the display area to the peripheral area, and inserted into the partition wall or passes through the partition wall. The wiring includes at least one through hole.

First claim

What is claimed is:

1 . A display apparatus comprising:
a substrate including a display area and a peripheral area; a wall arranged in the peripheral area; a first wiring arranged over the substrate, extending from the display area to the peripheral area; and a second wiring arranged between the substrate and the first wiring, wherein the first wiring includes at least one through hole, the first wiring is in direct contact with the second wiring below the wall from a first side of wall adjacent to the display area to a second side of the wall adjacent to an end of the substrate.

2 . The display apparatus of claim 1 , wherein the first wiring includes a plurality of through holes, and
the plurality of through holes are spaced apart from each other in one direction.

3 . The display apparatus of claim 1 , wherein the at least one through hole is arranged in the first wiring arranged inside the wall when viewed in a plan view.

4 . The display apparatus of claim 1 , wherein the first wiring includes a plurality of through holes, and
the plurality of through holes are arranged in a serpentine pattern.

5 . The display apparatus of claim 1 , wherein the wall includes:
a first layer arranged under the first wiring; and a second layer arranged on the first wiring.

6 . The display apparatus of claim 5 , wherein the wall further includes a third layer on the second layer.

7 . The display apparatus of claim 6 , wherein the second layer or the third layer includes a black material.

8 . The display apparatus of claim 6 , wherein the wall further includes a fourth layer on the third layer.

9 . The display apparatus of claim 5 , wherein the first layer and the second layer each include an organic material.

10 . The display apparatus of claim 1 , wherein the wall surrounds an outside of the display area.

11 . A display apparatus comprising:
a substrate including a display area and a peripheral area; a wall arranged in the peripheral area; a first wiring arranged over the substrate, extending from the display area to the peripheral area; a second wiring arranged between the substrate and the first wiring; and a touch wiring arranged over the substrate, extending from the display area to the peripheral area, and arranged on the wall, wherein the first wiring includes at least one through hole, and the first wiring is in direct contact with the second wiring below the wall from a first side of the wall adjacent to the display area to a second side of the wall adjacent to an end of the substrate.

12 . The display apparatus of claim 11 , wherein the first wiring includes a plurality of through holes, and
the plurality of through holes are spaced apart from each other in a lengthwise direction of the first wiring.

13 . The display apparatus of claim 11 , wherein the at least one through hole is arranged in the first wiring arranged inside the wall, when viewed in a plan view.

14 . The display apparatus of claim 11 , wherein the first wiring includes a plurality of through holes, and
the plurality of through holes are arranged in a serpentine pattern.

15 . The display apparatus of claim 11 , wherein the wall includes:
a first layer arranged under the first wiring; and a second layer arranged on the first wiring.

16 . The display apparatus of claim 15 , wherein the first layer and the second layer each include an organic material.

17 . The display apparatus of claim 15 , wherein the wall further includes a third layer on the second layer.

18 . The display apparatus of claim 17 , wherein the second layer or the third layer includes a black material.

19 . The display apparatus of claim 11 , wherein the wall surrounds an outside of the display area.

20 . The display apparatus of claim 19 , further comprising a terminal portion arranged in the peripheral area and configured to be connected to the first wiring and the touch wiring.

21 . The display apparatus of claim 20 , wherein the wall is arranged in a region between the terminal portion and the display area.

22 . A display apparatus comprising:
a substrate including a display area and a peripheral area; a wall arranged in the peripheral area; a first wiring arranged over the substrate, extending from the display area to the peripheral area; a second wiring arranged between the substrate and the first wiring; and a terminal portion arranged in the peripheral area, arranged apart from the display area, and configured to be connected to the wiring, wherein the wall is arranged between the terminal portion and the display area, and the first wiring includes at least one through hole, and the first wiring is in direct contact with the second wiring below the wall from a first side of the wall adjacent to the display area to a second side of the wall adjacent to an end of the substrate.

23 . The display apparatus of claim 22 , wherein the at least one through hole is arranged in the first wiring arranged inside the wall when viewed in a plan view.

24 . The display apparatus of claim 22 , wherein the first wiring includes a plurality of through holes, and
the plurality of through holes are arranged in a serpentine shape.

25 . The display apparatus of claim 22 , wherein the wall surrounds an outside of the display area.
