Abstract

A display device includes a first gate line and a data line intersecting each other, a pixel electrode, a switching element comprising a gate electrode connected to the first gate line, a source electrode connected to the data line, and a drain electrode connected to the pixel electrode, and a connecting portion which connects the drain electrode with the pixel electrode, and a distance between the data line and the connecting portion is less than a distance between the data line and the gate electrode in a first direction perpendicular to the data line.

Claims (28)

1. A display device comprising:

a first gate line and a data line which intersect each other;

a pixel electrode;

a switching element comprising a gate electrode connected to the first gate line, a source electrode connected to the data line, a drain electrode connected to the pixel electrode; and

a connecting portion which connects the drain electrode with the pixel electrode, a portion of the connecting portion overlapping the drain electrode,

wherein the connecting portion overlapping the drain electrode is between the data line and the gate electrode.

2. The display device as claimed in claim 1 , wherein the connecting portion is disposed between the data line and the gate electrode.

3. The display device as claimed in claim 2 , wherein the connecting portion is disposed in an area surrounded by the data line, the gate electrode, the first gate line, and the source electrode.

4. The display device as claimed in claim 1 , wherein the drain electrode and the pixel electrode are connected to each other through a contact hole positioned to an area corresponding to the connecting portion.

5. The display device as claimed in claim 1 , further comprising a compensation pattern which extends from the first gate line and overlaps the drain electrode.

6. The display device as claimed in claim 1 , wherein the source electrode comprises:

an electrode portion which overlaps the gate electrode; and

an extension portion which connects the electrode portion and the data line.

7. The display device as claimed in claim 6 , wherein the extension portion overlaps the first gate line.

8. The display device as claimed in claim 1 , further comprising a second gate line which intersects the data line and is adjacent to the first gate line, wherein the gate electrode is disposed between the first gate line and the second gate line.

9. The display device as claimed in claim 8 , wherein a distance between the first gate line and the second gate line is in a range of about 30 micrometers to about 41 micrometers.

10. The display device as claimed in claim 8 , further comprising a light blocking layer which overlaps the first gate line and the second gate line and is disposed between the first gate line and the second gate line.

11. The display device as claimed in claim 10 , wherein the light blocking layer has a width from about 35 micrometers to about 38 micrometers or from about 40 micrometers to about 47 micrometers.

12. The display device as claimed in claim 8 , wherein the gate electrode protrudes from the first gate line toward the second gate line.

13. The display device as claimed in claim 8 , further comprising a common line which intersects the first gate line and the second gate line.

14. The display device as claimed in claim 13 , wherein the switching element is disposed in an area surrounded by the first gate line, the second gate line, the data line, and the common line.

15. The display device as claimed in claim 13 , wherein the pixel electrode overlaps the gate electrode, the drain electrode, the common line, and the first gate line.

16. The display device as claimed in claim 1 , wherein the pixel electrode overlaps the first gate line.

17. The display device as claimed in claim 13 , wherein the pixel electrode overlaps the gate electrode, the source electrode, the common line, and the second gate line.

18. The display device as claimed in claim 8 , wherein the pixel electrode overlaps the source electrode and the second gate line.

19. The display device as claimed in claim 1 , wherein a distance between the data line and the connecting portion is less than a distance between the data line and the gate electrode in a first direction perpendicular to the data line in a plan view.

20. The display device as claimed in claim 1 , wherein the connecting portion overlapping the drain electrode is closer to the data line than the source electrode.

21. The display device as claimed in claim 1 , wherein the connecting portion overlapping the drain electrode is closer to the data line than the gate electrode.
