Abstract

A display device includes a driving gate electrode, a scan line separate from the driving gate electrode, a data line, a driving voltage line, and a semiconductor area including a first channel region overlapping the driving gate electrode and a shielding area overlapping the first data line. The display device also has a control line which includes a main line portion and a detour portion. The main line portion and the detour portion extend in different directions, and the semiconductor area includes a second channel region overlapping the first portion of the detour portion.

Claims (39)

1. A display device, comprising:

a driving gate electrode;

a scan line being spaced apart from the driving gate electrode and extending in a first direction;

a first data line to transmit a data signal, the first data line crossing the scan line;

a driving voltage line to transmit a driving voltage, the driving voltage line crossing the scan line;

a semiconductor area including a first channel region overlapping the driving gate electrode and a shielding area overlapping the first data line; and

a control line including a main line portion and a detour portion, the main line portion extending in the first direction and the detour portion including a first portion extending in a second direction crossing the first direction, wherein the semiconductor area includes a second channel region overlapping the first portion of the detour portion, and wherein

the first portion of the detour portion is disposed between a first side of the driving gate electrode extending in the second direction and the first data line.

2. The display device as claimed in claim 1 , wherein:

the semiconductor area includes a first connector connecting the shielding area and the first channel region and including the second channel region, and

the first connector crosses the first portion of the detour portion.

3. The display device as claimed in claim 2 , wherein the shielding area is connected to the driving voltage line and is to receive a driving voltage.

4. The display device as claimed in claim 3 , wherein the first portion of the detour portion includes a portion between the shielding area and the driving gate electrode.

5. The display device as claimed in claim 4 , wherein the first portion of the detour portion includes a bent area that includes at least one bend.

6. The display device as claimed in claim 5 , wherein the shielding area includes a recessed area adjacent to the bent area.

7. The display device as claimed in claim 5 , wherein the detour portion includes a second portion connected to the first portion of the detour portion and extending in the first direction.

8. The display device as claimed in claim 7 , wherein the second channel region is between the bent area of the detour portion and the second portion of the detour portion.

9. The display device as claimed in claim 7 , wherein the second portion of the detour portion is between the shielding area and the scan line.

10. The display device as claimed in claim 7 , wherein the second portion of the detour portion crosses the first data line.

11. The display device as claimed in claim 3 , wherein:

the semiconductor area includes a second connector connected to the shielding area, and

the driving voltage line is connected to the second connector through a contact hole of an insulating layer located between the second connector and the driving voltage line.

12. The display device as claimed in claim 1 , wherein the driving gate electrode is between the scan line and the main line portion of the control line.

13. The display device as claimed in claim 1 , wherein:

the driving voltage line includes an expansion area extending in the first direction, the expansion area overlapping the driving gate electrode to form a capacitor.

14. The display device as claimed in claim 13 , further comprising:

a second data line adjacent to the first data line,

wherein the shielding area overlaps the first and second data lines.

15. The display device as claimed in claim 13 , further comprising:

a third data line extending parallel to the first data line; and

another driving voltage line extending parallel to the driving voltage line,

wherein the driving gate electrode in a first pixel and another driving gate electrode in a second pixel are between the first data line and the third data line, and wherein the expansion area of the driving voltage line and another expansion area of the another driving voltage line are connected to each other.

16. The display device as claimed in claim 1 , wherein the detour portion includes a portion extending along a periphery of the shielding area and separated from the shielding area.

17. The display device as claimed in claim 1 , wherein:

the shielding area includes a recessed area that does not overlap the first data line, and

the recessed area is adjacent to the main line portion in the first direction.

18. The display device as claimed in claim 1 , wherein:

the semiconductor area includes a longitudinal part at a side opposite to the second channel region with respect to the driving gate electrode, and

the longitudinal part includes a portion crossing the main line portion.
