Display device

1. A display device, comprising:

a display panel comprising a display area in which pixels are arranged to display an image, and a non-display area located around the display area; and

a cover window comprising a light blocking area overlapping the non-display area of the display panel in a thickness direction of the display panel, and a through hole penetrating through the light blocking area,

wherein the display panel further comprises a first power supply line located in the non-display area to apply a first power supply voltage, and

wherein the first power supply line does not overlap the through hole in the thickness direction of the display panel.

2. The display device of claim 1 , wherein the display panel further comprises:

scan lines arranged in the display area and connected to the pixels; and

scan stages arranged in the non-display area and connected to the scan lines to apply scan signals.

3. The display device of claim 2 , wherein the scan stages comprise:

first scan stages overlapping the through hole in the thickness direction of the display panel; and

second scan stages not overlapping the through hole in the thickness direction of the display panel.

4. The display device of claim 3 , wherein the first power supply line overlaps the second scan stages in the thickness direction of the display panel.

5. The display device of claim 3 , wherein the first power supply line does not overlap the first scan stages in the thickness direction of the display panel.

6. The display device of claim 3 , wherein the display panel further comprises dummy scan stages located between corresponding scan stages adjacent to each other in one direction from among the scan stages in the non-display area.

7. The display device of claim 6 , wherein the dummy scan stages overlap the through hole in the thickness direction of the display panel.

8. The display device of claim 7 , wherein the first power supply line does not overlap the dummy scan stages.

9. The display device of claim 6 , wherein the dummy scan stages do not overlap the through hole in the thickness direction of the display panel.

10. The display device of claim 3 ,

wherein a length of any one of the first scan stages in one direction is longer than a length of any one of the second scan stages in the one direction, and

wherein a length of any one of the first scan stages in the other direction is shorter than a length of any one of the second scan stages in the other direction crossing the one direction.

11. The display device of claim 2 , wherein the display panel further comprises:

light emission lines connected to the pixels and located in the display area; and

light emission stages connected to the light emission lines to apply light emission signals.

12. The display device of claim 11 , wherein the light emission stages comprise:

first light emission stages overlapping the through hole in the thickness direction of the display panel; and

second light emission stages not overlapping the through hole in the thickness direction of the display panel.

13. The display device of claim 12 , wherein the first power supply line overlaps the second light emission stages in the thickness direction of the display panel.

14. The display device of claim 12 , wherein the first power supply line does not overlap the first light emission stages.

15. The display device of claim 12 ,

wherein a length of any one of the first light emission stages in one direction is longer than a length of any one of the second light emission stages in the one direction, and

wherein a length of any one of the first light emission stages in the other direction is shorter than a length of any one of the second light emission stages in the other direction crossing the one direction.

16. The display device of claim 11 , wherein the display panel further comprises dummy light emission stages located between corresponding light emission stages adjacent to each other in one direction from among the light emission stages in the non-display area.

17. The display device of claim 16 , wherein the dummy light emission stages do not overlap the through hole in the thickness direction of the display panel.

18. The display device of claim 16 , wherein the dummy light emission stages overlap the through hole in the thickness direction of the display panel.

19. The display device of claim 18 , wherein the first power supply line does not overlap the dummy light emission stages in the thickness direction of the display panel.

20. The display device of claim 1 , wherein the through hole overlaps a corner of the display panel in the thickness direction of the display panel.

21. The display device of claim 1 , further comprising:

a sensor device overlapping the through hole in the thickness direction of the display panel and sensing light.

22. A display device, comprising:

a display panel comprising a display area in which pixels are placed to display an image, and a non-display area located around the display area;

a sensor device overlapping the non-display area of the display panel in a thickness direction of the display panel to sense light; and

a cover window comprising a light blocking area overlapping the non-display area of the display panel in the thickness direction of the display panel, and a through hole penetrating through the light blocking area,

wherein the display panel further comprises a first power supply line located in the non-display area to apply a first power supply voltage,

wherein the through hole overlaps the sensor device in the thickness direction of the display panel, and

wherein the first power supply line does not overlap the sensor device in the thickness direction of the display panel.
