Display device
View Patent ↗A display device may include a display panel, an input sensing unit, and an alignment structure. The display panel may include a sealing member. The input sensing unit may be disposed on the display panel. The input sensing unit may include first-type sensor electrodes directly contacting a face of a first insulator of the display device, a first-type connector electrically connecting the first-type sensor electrodes, second-type sensor electrodes directly contacting the face of the first insulator of the display device, and a second-type connector electrically connecting the second-type sensor electrodes. The alignment structure may overlap the sealing member and may include a transparent member that directly contacts the face of the first insulator of the display device.
1. A display device comprising:
a display panel including a display area and a non-display area;
a sensing unit disposed on the display area of the display panel, wherein the sensing unit includes sensor electrodes, a connecting part electrically connecting adjacent sensor electrodes, a first insulating layer partially disposed between the sensor electrodes and the connecting part, and a second insulating layer disposed on the first insulating layer; and
an alignment mark overlapping the non-display area and including a first pattern part formed in a same conductive layer as the sensor electrodes and a second pattern part formed in a same conductive layer as the connecting part, wherein the first pattern part overlaps an opening that penetrates through at least one of the first insulating layer and the second insulating layer, wherein the opening penetrates through the second insulating layer and exposes the first pattern part, and wherein the second pattern part does not overlap the opening.
2. The display device of claim 1 , wherein the second pattern part overlaps a boundary of the first pattern part in a direction perpendicular to the display area of the display panel.
3. The display device of claim 1 , wherein the second pattern part includes an outer second pattern part and an inner second pattern part.
4. The display device of claim 3 , wherein the outer second pattern part surrounds the first pattern part and the inner second pattern part is surrounded by the first pattern part.
5. The display device of claim 1 , wherein the display panel includes a light emitting layer and an encapsulation layer disposed on the light emitting layer.
6. The display device of claim 5 , wherein the sensing unit is disposed directly on the encapsulation layer.
7. The display device of claim 1 , wherein the opening is disposed between opposite portions of the second pattern part.
8. The display device of claim 1 , wherein the opening penetrates through the second insulating layer and exposes the first insulating layer.
9. The display device of claim 1 , wherein the opening penetrates through both the first insulating layer and the second insulating layer.
10. The display device of claim 1 , wherein the first pattern part is in contact with the first insulating layer through the opening.
11. The display device of claim 1 , wherein the first pattern part includes a transparent conductive layer.
12. The display device of claim 11 , wherein the transparent conductive layer includes at least one of indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), and indium tin zinc oxide (ITZO).
13. The display device of claim 1 , wherein the second pattern part includes at least one of molybdenum, silver, titanium, copper, and aluminum.
14. A display device comprising:
a display panel including a sealing part;
a sensing unit disposed on the display panel, wherein the sensing unit includes sensor electrodes, a connecting part electrically connecting adjacent sensor electrodes, a first insulating layer partially disposed between the sensor electrodes and the connecting part, and a second insulating layer disposed on the first insulating layer; and
an alignment mark overlapping the sealing part and including a first pattern part formed in a same conductive layer as the sensor electrodes and a second pattern part formed in a same conductive layer as the connecting part, wherein an opening penetrates through the second insulating layer and exposes a conductive surface of the first pattern part, wherein the opening penetrates through the second insulating layer and exposes the first pattern part, and wherein the second pattern part does not overlap the opening.
15. The display device of claim 14 , wherein further comprising:
a sealing member overlapping the alignment mark.
16. The display device of claim 15 , wherein the display panel includes:
a base substrate;
a light emitting layer disposed on the base substrate; and
an encapsulation layer disposed on the light emitting layer, and
wherein the sealing member is disposed between the base substrate and the encapsulation layer.
17. The display device of claim 16 , wherein the sensing unit is disposed directly on the encapsulation layer.
18. The display device of claim 14 , wherein the second pattern part overlaps a boundary of the first pattern part.
19. The display device of claim 14 , wherein the second pattern part includes an outer second pattern part surrounding the first pattern part and an inner second pattern part surrounded by the first pattern part.
