Abstract

A display device includes first and second electrodes disposed on a substrate, the first and second electrodes extending in a direction and being parallel to each other, a first insulating layer disposed on the first and second electrodes, light-emitting elements disposed on the first insulating layer, the light-emitting elements having first end portions disposed on the first electrode and second end portions disposed on the second electrode, and a partition disposed on the first insulating layer and being parallel to the first electrode, the partition including a first part that overlaps the light-emitting elements, and second parts that do not overlap the light-emitting elements, wherein a vertical distance from a top surface of the first electrode to a top surface of the first part is equal to a vertical distance from the top surface of the first electrode to top surfaces of the second parts.

Claims (44)

1 . A display device comprising:

a first electrode and a second electrode disposed on a substrate, the first and second electrodes extending in a direction and being parallel to each other;

a first insulating layer disposed on the first and second electrodes;

light-emitting elements disposed on the first insulating layer, the light-emitting elements having first end portions disposed on the first electrode and second end portions disposed on the second electrode; and

a partition disposed on the first insulating layer and being parallel to the first electrode, the partition including:

a first part that overlaps the light-emitting elements; and

second parts that do not overlap the light-emitting elements,

wherein a vertical distance from a top surface of the first electrode to a top surface of the first part is equal to a vertical distance from the top surface of the first electrode to top surfaces of the second parts, and

wherein the second parts are distinct from the first part.

2 . The display device of claim 1 , wherein the second parts include:

a first extension; and

a second extension, wherein

the light-emitting elements are disposed between the first and second extensions.

3 . The display device of claim 2 , wherein the first part is disposed between the first and second extensions.

4 . The display device of claim 2 , wherein

the first extension overlaps the first electrode, and the second extension overlaps the second electrode.

5 . The display device of claim 1 , wherein the first part and the second parts intersect a direction in which the light-emitting elements extend.

6 . The display device of claim 1 , wherein the partition further includes third parts that extend in a direction that intersects the first electrode and connect the first part and the second parts.

7 . A display device comprising:

a first electrode and a second electrode disposed on a substrate, the first and second electrodes extending in a direction and being parallel to each other;

a first insulating layer disposed on the first and second electrodes;

light-emitting elements disposed on the first insulating layer, the light-emitting elements having first end portions disposed on the first electrode and second end portions disposed on the second electrode; and

a partition disposed on the first insulating layer and being parallel to the first electrode, the partition including:

a first part that overlaps the light-emitting elements; and

second parts that do not overlap the light-emitting elements,

wherein a vertical distance from a top surface of the first electrode to a top surface of the first part is equal to a vertical distance from the top surface of the first electrode to top surfaces of the second parts,

wherein the partition further includes third parts that extend in a direction that intersects the first electrode and connect the first part and the second parts, and

wherein the third parts include:

a first connector disposed on a side of the first part; and

a second connector disposed on another side of the first part.

8 . The display device of claim 7 , wherein the first and second connectors are arranged parallel to a direction in which the light-emitting elements extend, and do not overlap the light-emitting elements.

9 . A display device comprising:

a first electrode and a second electrode disposed on a substrate, the first and second electrodes extending in a direction and being parallel to each other;

a first insulating layer disposed on the first and second electrodes;

light-emitting elements disposed on the first insulating layer, the light-emitting elements having first end portions disposed on the first electrode and second end portions disposed on the second electrode; and

a partition disposed on the first insulating layer and being parallel to the first electrode, the partition including:

a first part that overlaps the light-emitting elements;

second parts that do not overlap the light-emitting elements; and

a bank disposed on the first insulating layer and partitioning an emission area in which the light-emitting elements are disposed,

wherein a vertical distance from a top surface of the first electrode to a top surface of the first part is equal to a vertical distance from the top surface of the first electrode to top surfaces of the second parts.

10 . The display device of claim 9 , wherein the partition is disposed in the emission area and does not overlap the bank.

11 . The display device of claim 9 , wherein the vertical distance from the top surface of the first electrode to the top surface of the first part is equal to a vertical distance from the top surface of the first electrode to a top surface of the bank.

12 . The display device of claim 9 , wherein the vertical distance from the top surface of the first electrode to the top surface of the first part is greater than the vertical distance from the top surface of the first electrode to the top surface of the bank.

13 . The display device of claim 9 , wherein the bank and the first part and the second parts of the partition are disposed directly on the first insulating layer and contact the first insulating layer.
