Organic light emitting display module and organic light emitting display device having the same
Provided is an organic light emitting display module including an active area, a pad area, and a boundary area between the active area and the pad area. Unlike the active area and the pad area, since the boundary area does not include an inorganic layer, less stress is applied to the boundary area when the boundary area is bent. Display panel pads and touch sensing member pads are disposed at the same height without having a height difference therebetween. Thus, a dummy pad may be added to remove the height difference between the display panel pads and the touch sensing member pads.
1. A display device comprising:
a base layer including a display area and a non-display area;
a display element layer comprising a display element on the display area;
a touch sensing member disposed on the display element layer and comprising a touch pattern on the display area;
a first pad disposed in the non-display area;
a second pad disposed on the first pad;
an organic layer disposed between the base layer and the second pad, and the organic layer partially covering the first pad; and
an inorganic layer disposed between the organic layer and the second pad, and the inorganic layer exposing at least a portion of the first pad, and
wherein the second pad is electrically connected to one of the display element layer and the touch sensing member.
2. The display device of claim 1 , wherein the organic layer is a layer of the display element layer, and
wherein the inorganic layer is a layer of the touch sensing member.
3. The display device of claim 2 , wherein the organic layer is disposed between the base layer and the display element.
4. The display device of claim 2 , wherein the inorganic layer is disposed between the display element and the touch pattern or disposed on the touch pattern.
5. The display device of claim 4 , wherein the touch pattern comprises a sensing pattern and a connection pattern disposed on a different layer from the sensing pattern,
wherein the touch sensing member further comprises:
a first insulation layer disposed between the connection pattern and the sensing pattern; and
a second insulation layer disposed between the display element and the first insulation layer, and
wherein the inorganic layer is at least one of the first insulation layer and the second insulation layer.
6. The display device of claim 5 , wherein the inorganic layer comprising both of the first insulation layer and the second insulation layer.
7. The display device of claim 6 , wherein the second pad disposed on a same layer with the sensing pattern.
8. The display device of claim 1 , further comprising an encapsulation layer disposed between the display element layer and the touch sensing member,
wherein the first pad and the second pad are disposed apart from the thin film encapsulation layer.
9. The display device of claim 1 , wherein the second pad contacts the portion of the first pad exposed from the inorganic layer.
10. The display device of claim 9 , wherein the first pad is electrically connected to the display element and the second pad is insulated from the touch sensing member.
11. The display device of claim 1 , wherein the first pad is insulated from the display element layer and the second pad is electrically connected to the touch sensing member.
12. The display device of claim 1 , wherein the second pad is electrically connected to the touch sensing member and the first pad is insulated from the second pad.
13. The display device of claim 1 , further comprising a floating dummy electrode disposed between the base layer and the first pad, wherein the first pad overlaps the floating dummy electrode in a plan view.
