Abstract

A display device includes pixels, scan lines, and data lines. A first driving gate electrode is disposed at a first pixel of the display device. A second driving gate electrode is disposed at a second pixel of the display device. A first driving voltage line includes a first extending part that overlaps a first driving gate electrode. A second driving voltage line includes a second extending part that overlaps a second driving gate electrode. A first pixel electrode of the first pixel overlaps the second driving gate electrode. The second extending part includes a first recess portion. A center line of the first recess portion is offset in a direction away from the first pixel electrode with respect to a center line of the second driving gate electrode.

Claims7

Dependent claims

A display device, comprising:

a first pixel;
a first driving gate electrode disposed in the first pixel;
a scan line extending substantially in a first direction;
and
a first driving voltage line crossing the scan line,
wherein the first driving voltage line includes:
a right portion extending substantially in a second direction that is perpendicular to the first direction;
a left portion extending substantially in the second direction;
a middle portion disposed between the right portion and the left portion, and extending from the right portion to the left portion in the first direction,
wherein a length of the middle portion in the second direction is less than a length of the left portion in the second direction,
wherein the right portion extends from the middle portion in the first direction, a length of the right portion in the second direction is greater than the length of the middle portion in the second direction,
wherein the middle portion and the right portion overlap the first driving gate electrode to form a capacitor,
wherein a width of the left portion in the first direction is less than a width of the right portion in the first direction, and
wherein an upper portion of the right portion protrudes more upward than an upper portion of the middle portion, and a lower portion of the right portion protrudes more downward than a lower portion of the middle portion in a plan view.
