Abstract

A display apparatus includes a substrate including a component area and a display area surrounding the component area, a driving voltage line extending in a first direction across the display area, a first horizontal connection line extending across the display area in a second direction and toward the component area, a first auxiliary horizontal connection line spaced apart from the first horizontal connection line, located between the first horizontal connection line and the component area, and extending in the second direction, and a transfer line extending in the second direction across the display area and toward the component area, and including a plurality of protrusions protruding in the first direction, wherein at least one of the plurality of protrusions is electrically connected to the first auxiliary horizontal connection line.

First claim

What is claimed is:

1 . A display apparatus comprising:
a substrate comprising a component area and a display area around the component area; a driving voltage line extending in a first direction across the display area; a first horizontal connection line extending across the display area in a second direction intersecting the first direction and toward the component area; a first auxiliary horizontal connection line spaced apart from the first horizontal connection line, located between the first horizontal connection line and the component area, and extending in the second direction; and a transfer line extending in the second direction toward the component area, and comprising a plurality of protrusions protruding in the first direction, wherein at least one of the plurality of protrusions is electrically connected to the first auxiliary horizontal connection line.

2 . The display apparatus of claim 1 , wherein one of the plurality of protrusions is electrically connected to the first auxiliary horizontal connection line.

3 . The display apparatus of claim 1 , wherein the at least one protrusion is located farther from the component area than an end of the transfer line.

4 . The display apparatus of claim 1 , wherein the transfer line and the first auxiliary horizontal connection line are disposed on a same layer.

5 . The display apparatus of claim 1 , wherein the transfer line and the first auxiliary horizontal connection line are integrally formed as a single body.

6 . The display apparatus of claim 1 , wherein the driving voltage line is disposed on the transfer line.

7 . The display apparatus of claim 6 , wherein the driving voltage line is electrically connected to one of the plurality of protrusions of the transfer line through a contact hole.

8 . The display apparatus of claim 1 , further comprising a plurality of pixel circuits located in the display area in rows extending in the second direction,
wherein, when n is a natural number of 2 or more, the first auxiliary horizontal connection line located in an n th row is electrically connected to the transfer line located in an n−1 th row.

9 . The display apparatus of claim 1 , further comprising a vertical connection line extending across the display area in the first direction and electrically connected to the first horizontal connection line.

10 . The display apparatus of claim 9 , wherein the vertical connection line and the driving voltage line are disposed on a same layer.

11 . The display apparatus of claim 1 , further comprising a second horizontal connection line extending across the display area in the second direction,
wherein the substrate further comprises a peripheral area outside the display area, wherein a first end of the second horizontal connection line is located in the peripheral area on one side of the display area, and a second end of the second horizontal connection line is located in the peripheral area on the other side of the display area.

12 . The display apparatus of claim 11 , wherein at least one of the first end and the second end of the second horizontal connection line is electrically connected to a constant voltage line in the peripheral area.

13 . The display apparatus of claim 11 , wherein both ends of the first horizontal connection line are located in the display area.

14 . The display apparatus of claim 11 , wherein the one end of the first horizontal connection line that is farther from the component area than the other end is located in the display area.

15 . The display apparatus of claim 11 , further comprising a first additional horizontal connection line spaced apart from the first horizontal connection line, located between the first horizontal connection line and the peripheral area, and extending in the second direction.

16 . The display apparatus of claim 15 , wherein an end of the first additional horizontal connection line that is farthest away from the component area is located in the peripheral area on a side of the display area.

17 . The display apparatus of claim 16 , wherein the end of the first additional horizontal connection line is electrically connected to a constant voltage line in the peripheral area.

18 . A display apparatus comprising:
a substrate; a driving voltage line extending across the display area in the first direction; a first component area and a second component area spaced apart from each other in a second direction intersecting a first direction, a display area around the first component area and the second component area; a horizontal connection line extending in the second direction across the display area and located between the first component area and the second component area; and a transfer line extending across the display area in the second direction and located between the first component area and the second component area, and comprising a plurality of protrusions protruding in the first direction, wherein at least one of the plurality of protrusions is electrically connected to the horizontal connection line.

19 . The display apparatus of claim 18 , wherein one of the plurality of protrusions is electrically connected to the horizontal connection line.

20 . The display apparatus of claim 18 , wherein the transfer line and the horizontal connection line are disposed on a same layer.

21 . The display apparatus of claim 18 , wherein the transfer line and the first auxiliary horizontal connection line are integrally formed as a single body.

22 . The display apparatus of claim 18 , wherein the driving voltage line is disposed over the transfer line.

23 . The display apparatus of claim 22 , wherein the driving voltage line is electrically connected to one of the plurality of protrusions of the transfer line through a contact hole.

24 . The display apparatus of claim 18 , further comprising a plurality of pixel circuits located in the display area in rows extending in the second direction,
wherein, when n is a natural number of 2 or more, the horizontal connection line located in an n th row is electrically connected to the transfer line located in an n−1 th row.
