Display device

1 . A display device comprising:

a substrate including a display area and a non-display area, wherein the non-display area has at least one contact area disposed on at least one side of the display area;

a planarization layer disposed on the substrate and including an organic material;

a pixel electrode disposed on the planarization layer and disposed in the display area;

a connection electrode disposed on the planarization layer and disposed in the non-display area, wherein the connection electrode is spaced apart from the pixel electrode;

a bank disposed on the planarization layer so as to cover a portion of the pixel electrode and a portion of the connection electrode, wherein the bank includes an organic material;

an organic light-emitting layer disposed on the pixel electrode;

a common electrode disposed on the bank and the organic light-emitting layer; and

an organic capping layer disposed on the common electrode,

wherein the common electrode is in contact with the connection electrode in the contact area,

wherein the common electrode has first holes defined therein for exposing the bank,

wherein the first holes of the common electrode are disposed in a portion of the non-display area adjacent to the contact area, and

wherein the organic capping layer is in contact with the bank through the first holes of the common electrode.

2 . The display device of claim 1 , wherein the connection electrode has first holes defined therein for exposing the planarization layer,

wherein the first holes of the connection electrode are disposed in the portion of the non-display area adjacent to the contact area, and
