Abstract

A display device includes a scan line extending in a first direction. A plurality of data lines cross the scan line. A driving voltage line crosses the scan line. An active pattern includes a plurality of channel regions and a plurality of conductive regions. A control line is connected to the plurality of data lines and the driving voltage line. The active pattern includes a shielding part overlapping at least one data line of the plurality of data lines. The control line includes a plurality of main line parts each extending in the first direction, and a detour part connecting two adjacent main line parts of the plurality of main line parts to each other. The detour part extends along a periphery of the active pattern and crosses the at least one data line of the plurality of data lines.

First claim

What is claimed is:

a scan line extending in a first direction;
a first data line crossing the scan line;
a driving voltage line crossing the scan line;
an active pattern including a plurality of channel regions and a plurality of conductive regions;
a control line crossing the first data line and the driving voltage line;
a driving gate electrode separated from the scan line and the control line, and disposed between the scan line and the control line in a plan view; and
a first pixel and a second pixel that are adjacent to each other in the first direction, each of the first pixel and the second pixel comprising the active pattern and the driving gate electrode,
wherein the control line includes a plurality of first portions each extending substantially in the first direction, and a second portion disposed between adjacent first portions of the plurality of first portions and connected to the adjacent first portions,
wherein the plurality of channel regions comprises:
a first channel region curved at least once and overlapping the driving gate electrode in the plan view; and
a second channel region overlapping the second portion of the control line,
the control line is bent between the first portion and the second portion adjacent to each other, and a middle portion of the second portion is closer to the driving gate electrode than the first portion is in a second direction perpendicular to the first direction,
wherein the first portion crosses the driving voltage line and first data line, and
wherein a planar shape of the first pixel and a planar shape of the second pixel are symmetrical to each other along the first direction.

2. The display device of claim 1 , wherein the driving gate electrode overlaps the second portion of the control line in the second direction such that the driving gate electrode is aligned with the second portion of the control line along the second direction.

3. The display device of claim 2 , wherein an imaginary straight line extending in the second direction and passing a center of the driving gate electrode passes the second portion of the control line.

4. The display device of claim 2 , wherein the second portion of the control line has a convex shape toward the driving gate electrode.

5. The display device of claim 1 , wherein:
the active pattern comprises a longitudinal part extending in the second direction, and
the second portion of the control line crosses the longitudinal part.

6. The display device of claim 1 , further comprising a second data line adjacent to the first data line,
wherein the first portion of the control line crosses the second data line.

7. The display device of claim 1 , wherein the driving voltage line comprises an extension part extending in the first direction and overlapping the driving gate electrode to form a capacitor.

8. The display device of claim 1 , further comprising:
a first light emitting diode comprising a first pixel electrode,
wherein the first pixel electrode is electrically connected to a first conductive region of the plurality of conductive regions of the active pattern via a first contact hole, and
wherein the second portion of the control line extends between the first contact hole and the driving gate electrode.

9. The display device of claim 8 , wherein the second portion of the control line has a symmetrical shape in the first direction.

10. The display device of claim 9 , further comprising:
a second light emitting diode comprising a second pixel electrode,
wherein the second pixel electrode is electrically connected to a second conductive region of the plurality of conductive regions of the active pattern via a second contact hole,
wherein the second portion of the control line forms a well shape, and
wherein the first contact hole and the second contact hole are disposed inside of the well shape of the second portion of the control line.

11. The display device of claim 1 , wherein a planar shape of the active pattern in the first pixel and a planar shape of the active pattern in the second pixel are symmetrical to each other along the first direction.
