Abstract

A display apparatus includes a substrate including a display area and a peripheral area, a data line arranged in the display area and extending in a first direction, a first horizontal connection line connected to the data line in the display area and extending in a second direction intersecting the first direction, a first vertical connection line in the display area, extending in the first direction, and having an end electrically connected to the first horizontal connection line and another end disposed closer to the peripheral area than the end, and a second horizontal connection line in the display area, extending in the second direction, and having an end electrically connected to the another end of the first vertical connection line and another end disposed farther from the data line than the end.

Claims (39)

1 . A display apparatus comprising:

a substrate including a display area and a peripheral area outside the display area;

a data line arranged in the display area and extending in a first direction;

a first horizontal connection line connected to the data line in the display area and extending in a second direction intersecting the first direction;

a first vertical connection line arranged in the display area, extending in the first direction, and having an end electrically connected to the first horizontal connection line and another end disposed closer to the peripheral area than the end of the first vertical connection line electrically connected to the first horizontal connection line; and

a second horizontal connection line arranged in the display area, extending in the second direction, and having an end electrically connected to the another end of the first vertical connection line and another end disposed farther from the data line than the end of the second horizontal connection line electrically connected to the another end of the first vertical connection line.

2 . The display apparatus of claim 1 , further comprising:

a second vertical connection line having an end electrically connected to the another end of the second horizontal connection line and another end disposed such that the second horizontal connection line is disposed between the another end of the second vertical connection line and the first horizontal connection line.

3 . The display apparatus of claim 2 , wherein the another end of the second vertical connection line is disposed in the peripheral area.

4 . The display apparatus of claim 1 , further comprising:

a second vertical connection line extending in the first direction and having an end electrically connected to the another end of the second horizontal connection line and another end disposed farther from the peripheral area than the end of the second vertical connection line electrically connected to the another end of the second horizontal connection line.

5 . The display apparatus of claim 4 , further comprising:

a third horizontal connection line arranged in the display area, extending in the second direction, and having an end electrically connected to the another end of the second vertical connection line and another end disposed farther from the data line than the end of the third horizontal connection line electrically connected to the another end of the second vertical connection line.

6 . The display apparatus of claim 5 , further comprising:

a third vertical connection line extending in the first direction and having an end electrically connected to the another end of the third horizontal connection line and another end disposed on a same side as the second horizontal connection line with respect to the third horizontal connection line.

7 . The display apparatus of claim 6 , wherein the another end of the third vertical connection line is disposed in the peripheral area.

8 . The display apparatus of claim 1 , wherein the data line and the first horizontal connection line are disposed on different layers.

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

10 . The display apparatus of claim 1 , further comprising:

a plurality of scan lines extending in the second direction.

11 . A display apparatus comprising:

a substrate including a display area and a peripheral area outside the display area;

a data line arranged in the display area and extending in a first direction; and

a connection line having an end connected to the data line in the display area and another end disposed in the peripheral area, and including a plurality of horizontal connection lines extending in a second direction intersecting the first direction and a plurality of vertical connection lines extending in the first direction,

wherein a first length in the second direction of one of the plurality of horizontal connection lines and a second length in the second direction of another one of the plurality of horizontal connection lines are different.

12 . The display apparatus of claim 11 , wherein a distance in the first direction from a portion of the peripheral area in which the another end of the connection line is disposed to one of the plurality of horizontal connection lines that is connected to the data line is greater than distances in the first direction from the portion of the peripheral area to others of the plurality of horizontal connection lines.

13 . The display apparatus of claim 11 , wherein distances in the first direction from a portion of the peripheral area in which the another end of the connection line is disposed to the plurality of horizontal connection lines decrease toward a center of the display area in the second direction.

14 . The display apparatus of claim 11 , wherein lengths of the plurality of horizontal connection lines in the second direction are randomly arranged.

15 . The display apparatus of claim 11 , wherein

the display area includes a plurality of pixel areas,

the first length corresponds to a width of one of the plurality of pixel areas in the second direction,

n is a natural number greater than 1, and

the second length is n times the first length.

16 . The display apparatus of claim 15 , wherein n is greater than or equal to 2.

17 . The display apparatus of claim 15 , wherein the plurality of horizontal connection lines include a first horizontal connection line having the first length and a second horizontal connection line having the second length alternatively arranged in the second direction.

18 . The display apparatus of claim 11 , wherein the plurality of vertical connection lines electrically connect the plurality of horizontal connection lines.

19 . The display apparatus of claim 11 , wherein the data line is disposed on a layer which is different from a layer on which the plurality of horizontal connection lines are disposed.

20 . The display apparatus of claim 11 , further comprising:

a plurality of scan lines extending in the second direction.
