## Abstract

A display device includes: a substrate including a display area, a peripheral area outside the display area, and a pad area in the peripheral area; a data line in the display area; and a first connection line in the display area and connected to the data line to transmit, to the data line, a signal from the pad area, wherein the first connection line includes a first portion in a first direction and a second portion bent from the first portion and in a second direction.

## Claims

### Claim 1

A display device comprising:
a substrate including a display area, a peripheral area outside the display area, and a pad area in the peripheral area;
a data line in the display area; and
a first connection line in the display area and connected to the data line,
wherein the first connection line has a serpentine shape, and
wherein the first connection line includes a first portion arranged in a first direction and a second portion bent from the first portion, the first portion being on a different layer from at least one of the second portion or the data line.

### Claim 2 (depends on 1)

The display device of claim 1, wherein the second portion extends in a second direction.

### Claim 3 (depends on 1)

The display device of claim 1, wherein the first direction is parallel to a lengthwise direction of a scan line in the display area.

### Claim 4 (depends on 1)

The display device of claim 1, wherein a second direction along which the second portion extends is parallel to a lengthwise direction of the data line.

### Claim 5 (depends on 1)

The display device of claim 1, wherein the data line and the first portion are on different layers.

### Claim 6 (depends on 1)

The display device of claim 1, wherein the first portion and the second portion are on different layers.

### Claim 7 (depends on 1)

The display device of claim 1, wherein the first portion and the second portion are at a same layer.

### Claim 8 (depends on 1)

The display device of claim 1, wherein at least one of the first portion or the second portion extends in a straight line.

### Claim 9 (depends on 1)

The display device of claim 1, wherein at least a portion of the first connection line overlaps at least one of a scan line or a pixel electrode on a plane.

### Claim 10 (depends on 1)

The display device of claim 1, further comprising a second connection line arranged in the peripheral area, connected to the first connection line, and located in the pad area.

### Claim 11 (depends on 1)

The display device of claim 1, wherein the display area includes a plurality of pixel areas arranged in rows and columns, and
one scan line passing through pixel areas in a same column among the plurality of pixel areas crosses the first connection line once or twice on a plane.

### Claim 12 (depends on 1)

The display device of claim 1, wherein a distance from a portion of the first connection line, which is connected to the pad area, to the pad area is different from a distance from the pad area to a portion of the first connection line, which is connected to the data line.

### Claim 13 (depends on 1)

The display device of claim 1, wherein a point of the first connection line, which has a maximum distance from the pad area to the first connection line, is between a portion of the first connection line, which is connected to the pad area, and a portion of the first connection line, which is connected to the data line.

### Claim 14 (depends on 1)

The display device of claim 1, wherein the data line comprises a plurality of data lines spaced apart from each other in the display area,
the first portion overlaps at least one of the plurality of data lines on a plane, and the first portion does not overlap a rest of the plurality of data lines except for the data lines overlapping on a plane.

### Claim 15 (depends on 1)

The display device of claim 1, wherein a corner of an edge of the display area is round.

### Claim 16

A display device comprising:
a substrate including a display area, a peripheral area outside the display area, and a pad area in the peripheral area;
a first data line in the display area; and
a first connection line in the display area and connected to the first data line to transmit, to the first data line, a signal from the pad area,
wherein the first connection line extends in a direction different from a longitudinal direction of the first data line, and
wherein the first connection line includes a first portion arranged in a first direction and a second portion bent from the first portion, the first portion being on a different layer from at least one of the second portion or the first data line.

### Claim 17 (depends on 16)

The display device of claim 16, wherein the first portion and the second portion are at different layers or at a same layer.

### Claim 18 (depends on 16)

The display device of claim 16, further comprising a plurality of second data lines in the display area and each extending in a second direction,
wherein at least one of the first data line or the second data line is at a different layer from at least one of the first portion or the second portion.

### Claim 19 (depends on 16)

The display device of claim 16, further comprising: a plurality of second data lines in the display area and each extending in a second direction; and
a third connection line in the peripheral area and having one end connected to one of the second data lines and an other end located in the pad area.

### Claim 20 (depends on 16)

The display device of claim 16, wherein at least a portion of the first connection line overlaps at least one of a scan line or a pixel electrode on a plane.

### Claim 21 (depends on 16)

The display device of claim 16, wherein a distance from a portion of the first connection line, which is connected to the pad area, to the pad area is different from a distance from the pad area to a portion of the first connection line, which is connected to the first data line.

### Claim 22 (depends on 16)

The display device of claim 16, wherein a point of the first connection line, which has a maximum distance from the pad area to the first connection line, is between a portion of the first connection line, which is connected to the pad area, and a portion of the first connection line, which is connected to the first data line.

### Claim 23 (depends on 1)

The display device of claim 1, wherein the substrate further includes a dummy area between the display area and the peripheral area.
