Abstract

A display apparatus includes a substrate including a display area and a peripheral area at least partially surrounding the display area. A corner of an edge of the display area is curved. The peripheral area includes a pad area. A data line is disposed in the display area. A first connecting line is disposed in the display area and is connected to the data line to transmit a signal from the pad area to the data line. The first connecting line includes a first portion extending tram the edge in a direction away from the peripheral area and a second portion bent with respect to the first portion and extending towards the corner.

First claim

What is claimed is:

1. A display apparatus comprising:
a substrate comprising a display area and a peripheral area at least partially surrounding the display area, wherein the peripheral area comprises a pad area;
a data line disposed in the display area; and
a first connecting line disposed in the display area and connected to the data line, the first connecting line transmitting a signal from a pad of the pad area to the data line,
wherein the display area comprises a dummy area adjacent to a boundary between the display area and the peripheral area,
wherein the first connecting line comprises a first portion disposed within the display area, extending from an edge of the display area adjacent to the pad area in a direction away from the peripheral area, and a second portion disposed within the display area and bent with respect to the first portion and extending towards a corner of the edge of the display area,
wherein the second portion is connected to the data line in the dummy area.

2. The display apparatus of claim 1 ,
wherein, in the first connecting line, the first portion and the second portion extend in a direction inclined with respect to a first direction in which the data line extends.

3. The display apparatus of claim 2 ,
wherein the first portion and the second portion of the first connecting line extend in a zigzag shape.

4. The display apparatus of claim 2 ,
wherein the first portion and the second portion of the first connecting line extend linearly.

5. The display apparatus of claim 1 ,
wherein the data line and the first connecting line are on different layers from each other.

6. A display apparatus comprising:
a substrate comprising a display area and a peripheral area at least partially surrounding the display area, wherein the peripheral area comprises a pad area;
a data line disposed in the display area; and
a first connecting line disposed in the display area and connected to the data line, the first connecting line transmitting a signal from the pad area to the data line,
wherein the display area comprises a dummy area adjacent to a boundary between the display area and the peripheral area,
wherein the first connecting line comprises a first portion, extending from an edge of the display area in a direction away from the peripheral area, and a second portion bent with respect to the first portion and extending towards a corner of the edge of the display area,
wherein the second portion is connected to the data line in the dummy area, and
wherein the first connecting, line further comprises a third portion extending in a first direction in which the data line extends and/or a fourth portion extending in a second direction perpendicular to the first direction.

7. The display apparatus of claim 1 ,
further comprising a second connecting line disposed in the peripheral area and comprising a first end connected to the first portion of the first connecting line and a second end disposed in the pad area.

8. A display apparatus comprising:
a substrate comprising a display area and a peripheral area at least partially surrounding the display area, wherein the peripheral area comprises a pad area;
a plurality of scan lines disposed in the display area and each scan line of the plurality of scan lines extending in a first direction;
a plurality of first data lines disposed in the display area and each first data line of the plurality of first data lines extending in a second direction perpendicular to the first direction; and
a plurality of first connecting lines disposed in the display area and connected to the plurality of first data lines to transmit a signal from pads of the pad area to the plurality of first data lines,
wherein each of the plurality of first connecting lines comprises a first portion disposed in the display area, extending from an edge of the display area adjacent to the pad area in a direction away from the peripheral area, and a second portion disposed in the display area and bent from the first portion and extending towards a corner of the edge of the display area,
wherein each of the first portion and the second portion alternates between a first sub-portion extending parallel to at least one of the plurality of scan lines and a second sub-portion extending parallel to at least one of the plurality of first data lines.

9. The display apparatus of claim 8 ,
wherein, in each of the plurality of first connecting lines, the first portion and the second portion extend in a direction inclined with respect to the first direction while alternating between the first sub-portion and the second sub-portion.

10. The display apparatus of claim 8 ,
wherein the plurality of first connecting lines are on a different layer from the plurality of scan lines.

11. The display apparatus of claim 10 ,
wherein the first sub-portion at least partially overlaps the at least one scan line.

12. The display apparatus of claim 8 ,
wherein the plurality of first connecting lines are on a different layer from the plurality of first data lines.

13. The display apparatus of claim 12 ,
wherein the second sub-portion at least partially overlaps the at least one first data line.

14. The display apparatus of claim 8 ,
wherein the first sub-portion has a length that is n times (where n is a positive integer) as much as a first length corresponding to a distance between two adjacent first data lines, and the second sub-portion has a length that is m times (where in is a positive integer) as much as a second length corresponding to a distance between two adjacent scan lines.

15. The display apparatus of claim 8 ,
wherein the first sub-portions of adjacent first connecting lines are spaced apart from each other by a length that is n times (where n is a positive integer) as much as a second length corresponding to a distance between two adjacent scan lines, and
the second sub-portions of the adjacent first connecting lines are spaced apart from each other by a length that is m times (where m is a positive integer) as much as a first length corresponding to a distance between two adjacent first data lines.

16. The display apparatus of claim 8 ,
wherein each of the plurality of first connecting lines further comprises a third portion connected to the first portion and extending linearly in the first direction and a fourth portion connected to the second portion and extending linearly in the first direction.

17. The display apparatus of claim 16 ,
wherein each of the plurality of first connecting lines further comprises a fifth portion disposed between the first portion and the second portion and extending linearly in the first direction.

18. The display apparatus of claim 8 ,
wherein the display area comprises a dummy area adjacent to a boundary between the display area and the peripheral area,
