Abstract

A display device includes a pixel including an emission area and a non-emission area, a bank disposed in the non-emission area, an insulating layer disposed on the bank, light emitting elements disposed in the emission area, and connection electrodes electrically connected to the light emitting elements. The insulating layer overlaps a first area of the bank, and includes an opening exposing a second area of the bank in a plan view. The connection electrodes overlap the first area of the bank in a plan view.

Claims (30)

1 . A display device comprising:

a pixel including an emission area and a non-emission area;

a bank disposed in the non-emission area;

an insulating layer disposed on the bank;

light emitting elements disposed in the emission area; and

connection electrodes electrically connected to the light emitting elements, wherein

the insulating layer overlaps a first area of the bank, and includes an opening exposing a second area of the bank in a plan view, and

the connection electrodes overlap the first area of the bank in a plan view,

wherein the connection electrodes do not overlap the opening of the insulating layer in a plan view.

2 . The display device of claim 1 , wherein the insulating layer overlaps a side surface of the bank in a plan view.

3 . The display device of claim 1 , wherein the second area of the bank is water repellant.

4 . The display device of claim 1 , further comprising:

electrodes spaced apart from each other in the emission area,

wherein the light emitting elements are disposed between the electrodes.

5 . The display device of claim 4 , wherein the insulating layer is disposed between the electrodes and the light emitting elements.

6 . The display device of claim 1 , wherein the connection electrodes include:

a first connection electrode electrically connected to first end portions of the light emitting elements; and

a second connection electrode electrically connected to second end portions of the light emitting elements.

7 . The display device of claim 6 , wherein the first connection electrode and the second connection electrode are disposed on a same layer.

8 . The display device of claim 6 , further comprising:

another insulating layer disposed between the first connection electrode and the second connection electrode.

9 . A display device comprising:

a pixel including an emission area and a non-emission area;

a bank disposed in the non-emission area;

an insulating layer disposed on the bank;

light emitting elements disposed in the emission area; and

connection electrodes electrically connected to the light emitting elements, wherein

the insulating layer overlaps a first area of the bank, and includes an opening exposing a second area of the bank in a plan view, and

the connection electrodes overlap the first area of the bank in a plan view,

wherein a thickness of the first area of the bank is greater than a thickness of the second area of the bank.
