Abstract

A display device includes a display panel including a main area and a sensor area. Sensor devices overlap the sensor area of the display panel in a thickness direction of the display panel. The display panel includes first subpixels, which are disposed in the sensor area, and second subpixels, which are disposed in the main area. The number of transistors of each of the first subpixels is different from the number of transistors of each of the second subpixels.

First claim

What is claimed is:

1. A display device, comprising:
a plurality of scan lines extending in a first direction;
a plurality of data lines extending in a second direction perpendicular to the first direction;
a plurality of driving voltage lines extending in the second direction;
a plurality of subpixels, each of the plurality of subpixels is connected to one of the plurality of scan lines, one of the plurality of data lines, and one of the plurality of driving voltage lines; and
a light-transmitting area not overlapping the plurality of scan lines, the plurality of data lines, the plurality of driving voltage lines, and the plurality of subpixels,
wherein the plurality of subpixels include a first subpixel connected to a first driving voltage line of the plurality of driving voltage lines and a second subpixel connected to a second driving voltage line of the plurality of driving voltage lines, and
wherein the first driving voltage line is connected to a first power supply connecting line, and the second driving voltage line is connected to a second power supply connecting line, in an area adjacent to the light-transmitting area.

2. The display device of claim 1 , the plurality of driving voltage lines are included in a first metal layer, and the first power supply connecting line and the second power supply connecting line are included in a second metal layer.

3. The display device of claim 1 , wherein the first power supply connecting line is connected to the first driving voltage line through a first connecting contact hole, and the second power supply connecting line is connected to the second driving voltage line through a second connecting contact hole.

4. The display device of claim 3 , wherein each of the first connecting contact hole and the second connecting contact hole penetrates a planarization film disposed on the first driving voltage line and the second driving voltage line, and
wherein the first power supply connecting line and the second power supply voltage line are disposed on the planarization film.

5. The display device of claim 1 , wherein the first subpixel and the second subpixel are disposed in the first direction, and
wherein a third subpixel does not overlap the first subpixel and the second subpixel in the second direction.

6. The display device of claim 1 , wherein the first subpixel is connected to a first data line among the plurality of data lines, and the second subpixel is connected to a second data line among the plurality of data lines, and
wherein the first data line, the second data line, the first power supply connecting line, and the second power supply connecting line do not overlap each other.

7. The display device of claim 6 , further comprising an initialization voltage line to which an initialization voltage is applied, and
wherein the initialization voltage line overlaps one of the first data line and the second data line.

8. The display device of claim 6 , wherein a first scan line among the plurality of scan lines overlaps one of the first power supply connecting line and the second power supply connecting line.

9. The display device of claim 8 , wherein a second scan line among the plurality of scan lines overlaps one of the first data line and the second data line.

10. The display device of claim 8 , further comprising an emission line to which an emission signal is applied overlaps other one of the first power supply connecting line and the second power supply connecting line.
