Organic light-emitting display device having bank insulating layer

1. An organic light-emitting display device comprising:

a lower electrode disposed on a lower substrate, the lower substrate having a non-display area including a side edge surface of the lower substrate;

a bank insulating layer covering an edge of the lower electrode, the bank insulating layer including a side surface facing and disposed closest to the non-display area including the side edge surface of the lower substrate;

an organic light-emitting layer disposed on the lower electrode, the organic light-emitting layer extending to the bank insulating layer, the organic light-emitting layer including a side surface being vertically aligned with the side surface of the bank insulating layer; and

an upper electrode disposed on the organic light-emitting layer, the upper electrode including an end portion being disposed closer than the edge of the lower electrode to the side edge surface of the lower substrate, the end portion of the upper electrode having the same material as another portion of the upper electrode, the end portion having an upper surface; and

a protective layer disposed on the upper surface of the end portion,

wherein the vertically aligned side surfaces of the bank insulating layer and the organic light-emitting layer are in contact with the upper electrode; so that the end portion of the upper electrode is disposed on the same layer as the lower electrode, and

wherein a lower surface of the end portion of the upper electrode towards the lower substrate is in contact with the same layer as a lower surface of the lower electrode towards the lower substrate.

2. The organic light-emitting display device according to claim 1 , further comprising:

a capping layer disposed on an upper surface of the upper electrode; and

the protective layer being further disposed on the capping layer, the protective layer extending to the side surface of the bank insulating layer.

3. The organic light-emitting display device according to claim 2 , wherein the capping layer includes a side surface being vertically aligned with a surface of the upper electrode which is disposed on the side surface of the bank insulating layer.

4. The organic light-emitting display device according to claim 1 , wherein the vertically aligned side surfaces of the bank insulating layer and the organic light-emitting layer form a slightly slanted vertical line.

5. The organic light-emitting display device according to claim 1 , wherein the protective layer is further on the organic light-emitting layer and the bank insulating layer, and

wherein the protective layer covers the side surface of the bank insulating layer and the side surface of the organic light-emitting layer, and contacts the lower substrate.

6. The organic light-emitting display device according to claim 5 , further comprising an adhesive layer covering the protective layer, and contacting the lower substrate.

7. The organic light-emitting display device according to claim 1 , further comprising a planarization layer between the lower substrate and the lower electrode,

wherein the planarization layer extends between the lower substrate and the end portion of the upper electrode, and

wherein the lower electrode, the end of the upper electrode, and the bank insulation layer contact the planarization layer.
