Abstract

A display device includes a display area, and a dummy area disposed on one side of the display area, where each of the display area and the dummy area includes a first island pattern and a second island pattern disposed to be spaced apart from each other, and a connection pattern connecting the first island pattern and the second island pattern to each other, and the dummy area includes a dummy common electrode and a common connection electrode electrically connected to the dummy common electrode, which are disposed in each of the first island pattern and the second island pattern thereof.

Claims (12)

1 . An electronic device including a display device displaying an image comprising:

wherein the display device includes:

a display area; and

a dummy area disposed on one side of the display area,

wherein each of the display area and the dummy area includes:

a first island portion and a second island portion disposed to be spaced apart from each other; and

a connection portion connecting the first island portion and the second island portion to each other, and

the dummy area includes a dummy electrode and a connection electrode electrically connected to the dummy electrode, which are disposed in each of the first island portion and the second island portion thereof.

2 . The electronic device of claim 1 , wherein the display area includes a light emitting element disposed in in each of the first island portion and the second island portion thereof, wherein the light emitting element includes a first electrode of the light emitting element, an interposition layer disposed on the first electrode of the light emitting element, and a second electrode of the light emitting element disposed on the interposition layer.

3 . The electronic device of claim 2 , wherein the dummy area includes a dummy interposition layer disposed in each of the first island portion and the second island portion thereof, wherein the dummy interposition layer includes a same material as the interposition layer.

4 . The electronic device of claim 3 , wherein the second electrode of the light emitting element is connected to the connection electrode through a contact hole defined through an insulating layer interposed between the second electrode of the light emitting element and the connection electrode.

5 . The electronic device of claim 4 , wherein the contact hole does not overlap the dummy interposition layer.
