Abstract

A display device includes a through portion passing through a display layer. The display includes a plurality of scan lines above the substrate and extending in a first direction, a plurality of data lines extending in a second direction, and a plurality of pixels connected to the scan lines and data lines. The data lines include a first data line and a second data line disconnected by the through portion, and a third data line spaced apart from the through portion along the first direction. The first data line is electrically connected with the third data line.

Claims

1. A display device, comprising:

a substrate;

a display layer on the substrate, the display layer includes a plurality of scan lines extending in a first direction, a plurality of data lines extending in a second direction crossing the first direction, and a plurality of pixels connected to the plurality of scan lines and the plurality of data lines; and

a through portion passing through the substrate and the display layer,

wherein the plurality of data lines include a first data line and a second data line disconnected by the through portion and a third data line spaced apart from the through portion along the first direction, and wherein the first data line is electrically connected with the third data line.

2. The display device as claimed in claim 1, wherein the first data line and the second data line are spaced apart from each other in the second direction, with the through portion therebetween.

3. The display device as claimed in claim 1, wherein the substrate includes:

a display area including the display layer; and

a non-display area surrounding the display area.

4. The display device as claimed in claim 3, wherein at least a partial region of the non-display area is bent with respect to the display area.

5. The display device as claimed in claim 3, further comprising:

a data connection line to connect the first data line to the third data line.

6. The display device as claimed in claim 5, wherein the data connection line is integrally formed with the first data line and the third data line and includes a same material as the first data line and the third data line.

7. The display device as claimed in claim 5, wherein the data connection line is bent in the non-display area.

8. The display device as claimed in claim 5, further comprising:

an insulating layer between the data connection line and the first and third data lines, and wherein the data connection line is connected to the first data line and the third data line via a contact hole passing through the insulating layer.

9. The display device as claimed in claim 8, wherein the data connection line is in the display area.

10. The display device as claimed in claim 1, wherein the plurality of data lines includes a fourth data line spaced apart from the through portion along the first direction, wherein the third data line is between the through portion and the fourth data line, and wherein the fourth data line extends toward an edge of the substrate.

11. The display device as claimed in claim 10, further comprising:

a metallic layer to induce a parasitic capacitance between an extended portion of the fourth data line and the metallic layer.

12. The display device as claimed in claim 1, wherein the plurality of pixels includes:

a first pixel connected to the first data line;

a second pixel connected to the second data line; and

a third pixel connected to the third data line and in a row in which the first pixel is disposed, and wherein a data signal of the first pixel is equal to a data signal of the third pixel.

15. The display device as claimed in claim 12, wherein a scan signal of the first pixel is independent from a scan signal of the third pixel.

16. The display device as claimed in claim 1, further comprising:

a data driver connected to the plurality of data lines,

the second data line is closer to the data driver than the first data line.

17. The display device as claimed in claim 1, wherein each of the plurality of pixels includes:

a pixel circuit including a thin film transistor (TFT) and a storage capacitor; and
