Abstract

A display device includes a substrate including a display area and a non-display area; pixels disposed in the display area and including respective light emitting units; a first conductive pattern disposed between the pixels; and a power source line disposed in the non-display area and electrically connected to the first conductive pattern. Each of the light emitting units includes a light emitting element, a first pixel electrode disposed on a first end of the light emitting element, and a second pixel electrode disposed on a second end of the light emitting element. The first conductive pattern and the second pixel electrode are disposed on a same layer.

First claim

What is claimed is:

1 . A display device comprising:
a substrate including a display area and a non-display area; pixels disposed in the display area and including light emitting units; a first conductive pattern disposed between the pixels; and a power source line disposed in the non-display area and electrically connected to the first conductive pattern, wherein each of the light emitting units includes:
a light emitting element;
a first pixel electrode disposed on a first end of the light emitting element; and
a second pixel electrode disposed on a second end of the light emitting element, and
wherein the first conductive pattern and the second pixel electrode are disposed on a same layer.

2 . The display device of claim 1 , wherein the first conductive pattern includes:
first pattern portions extending in a first direction in the display area; and second pattern portions extending in a second direction in the display area.

3 . The display device of claim 2 , wherein the first conductive pattern further includes a third pattern portion disposed in the non-display area and connected to the first pattern portions and the second pattern portions.

4 . The display device of claim 3 , wherein the third pattern portion surrounds the display area when viewed on a plane.

5 . The display device of claim 1 , wherein
the first conductive pattern extends to the non-display area and overlaps the power source line, and the first conductive pattern is directly connected to the power source line.

6 . The display device of claim 1 , further comprising:
a first pad electrically connected to the power source line, wherein the first conductive pattern is not directly connected to the power source line, and the first conductive pattern is electrically connected to the first pad.

7 . The display device of claim 1 , wherein the first conductive pattern and the second pixel electrodes of the light emitting units are separated from each other.

8 . The display device of claim 1 , wherein the power source line is electrically connected to the second pixel electrodes of the light emitting units.

9 . The display device of claim 8 , wherein the first conductive pattern and the second pixel electrodes of the light emitting units are integral with each other.

10 . The display device of claim 1 , wherein
the first pixel electrodes of the light emitting units and the first conductive pattern are disposed on different layers, and the first pixel electrodes of the light emitting units and the second pixel electrodes of the light emitting units are disposed on different layers.

11 . The display device of claim 10 , further comprising:
a second conductive pattern overlapping the first conductive pattern and electrically connected to the first conductive pattern.

12 . The display device of claim 11 , wherein the second conductive pattern and the first pixel electrodes of the light emitting units are disposed on a same layer.

13 . The display device of claim 11 , wherein
the first conductive pattern has a mesh shape and includes:
first pattern portions extending in a first direction in the display area; and
second pattern portions extending in a second direction in the display area, and
the second conductive pattern has a mesh shape and includes:
third pattern portions overlapping the first pattern portions; and
fourth pattern portions overlapping the second pattern portions.

14 . The display device of claim 11 , wherein the second conductive pattern and the first pixel electrodes of the light emitting units are separated from each other.

15 . The display device of claim 1 , wherein the pixels further include pixel circuits electrically connected to the respective light emitting units.

16 . The display device of claim 15 , further comprising:
a circuit layer disposed on a surface of the substrate and including the power source line and the pixel circuits of the pixels; and a display layer disposed on the circuit layer and including the first conductive pattern and the light emitting units of the pixels.

17 . The display device of claim 16 , further comprising:
a color filter layer and an encapsulation layer that are disposed above the display layer.

18 . The display device of claim 17 , wherein the color filter layer and the encapsulation layer are disposed above the surface of the substrate where the circuit layer and the display layer are disposed.

19 . A display device comprising:
pixels including light emitting units, each of the light emitting units including:
a light emitting element; and
pixel electrodes electrically connected to the light emitting element; and
a conductive pattern having a mesh shape and disposed around the pixels to surround the light emitting units, wherein the conductive pattern and at least one of the pixel electrodes are disposed on a same layer.
