Abstract

A display device includes a lower electrode, middle electrodes above the lower electrode, and spaced apart from each other, upper electrodes above the middle electrodes, and spaced apart from each other, light emitting elements between the upper electrodes, and connection electrodes above the light emitting elements, and electrically connected to the light emitting elements.

Claims (15)

1 . A display device comprising:

a lower electrode;

middle electrodes above the lower electrode, and spaced apart from each other;

upper electrodes above and overlapping the middle electrodes in a thickness direction with a second insulating layer therebetween, and spaced apart from each other;

light emitting elements between the upper electrodes; and

connection electrodes above the light emitting elements, and electrically connected to the light emitting elements.

2 . The display device of claim 1 , wherein an interval between the middle electrodes is less than a length of the light emitting elements.

3 . The display device of claim 1 , wherein an interval between the upper electrodes is greater than a length of the light emitting elements.

4 . The display device of claim 1 , wherein the light emitting elements completely overlap the lower electrode in the thickness direction.

5 . The display device of claim 1 , further comprising a first insulating layer between the lower electrode and the middle electrodes.

6 . The display device of claim 1 , further comprising a third insulating layer above the upper electrodes.

7 . The display device of claim 6 , wherein the light emitting elements are above the third insulating layer.

8 . The display device of claim 1 , further comprising a fourth insulating layer above the light emitting elements.

9 . The display device of claim 8 , wherein the connection electrodes are above end portions of the light emitting elements exposed by the fourth insulating layer.

10 . The display device of claim 1 , wherein an interval between the upper electrodes is greater than an interval between the middle electrodes.
