Abstract

A display device includes a substrate and a display element layer disposed on the substrate and emitting light. The display element layer includes a first electrode electrically connected to a portion of a first light emitting element, a second electrode electrically connected to another portion of the first light emitting element, and at least one insulating structure disposed on the substrate and having a convex shape protruding from the substrate. The first light emitting element is disposed in a space of the at least one insulating structure. A method of manufacturing the display device is also disclosed.

Claims (29)

1. A display device comprising: a substrate; and a display element layer disposed on the substrate and emitting light, the display element layer including: a first electrode electrically connected to a portion of a first light emitting element; a second electrode electrically connected to another portion of the first light emitting element; and at least one insulating structure disposed directly on both the first electrode and the second electrode and having a convex shape protruding from the substrate, wherein the first light emitting element is disposed in a space of the at least one insulating structure, and the space of the at least one insulating structure is an empty space.

2. The display device of claim 1 , wherein the space of the at least one insulating structure is separated from outside of the at least one insulating structure.

3. A display device comprising:

a substrate; and

a display element layer disposed on the substrate and emitting light, the display element layer including:

a first electrode electrically connected to a portion of a first light emitting element;

a second electrode electrically connected to another portion of the first light emitting element; and

at least one insulating structure disposed on the substrate and having a convex shape protruding from the substrate, wherein

the first light emitting element is disposed in a space of the at least one insulating structure, and

the at least one insulating structure includes a hole through which the space is exposed to outside of the at least one insulating structure.

4. The display device of claim 1 , wherein

the at least one insulating structure includes a first insulating structure and a second insulating structure adjacent to each other, and

the first light emitting element is disposed in the space of each of the first insulating structure and the second insulating structure.

5. The display device of claim 4 , wherein

the first electrode or the second electrode is disposed between the first insulating structure and the second insulating structure, and

the first electrode or the second electrode includes:

a first portion electrically connected to the first light emitting element in the space of the first insulating structure; and

a second portion electrically connected to the first light emitting element in the space of the second insulating structure.

6. The display device of claim 4 , wherein

the first electrode and the second electrode each include a portion exposed to outside of the first insulating structure and the second insulating structure, and

the display element layer includes a second light emitting element disposed between the first insulating structure and the second insulating structure and electrically connected to the portion of the first electrode and the portion of the second electrode.

7. The display device of claim 1 , wherein the display element layer further includes a reflective layer disposed on a surface of the at least one insulating structure and reflecting the light emitted from the first light emitting element.

8. The display device of claim 7 , wherein the reflective layer includes:

a first reflective layer overlapping the first electrode; and

a second reflective layer overlapping the second electrode,

wherein the first reflective layer is electrically connected to the first electrode and the second reflective layer is electrically connected to the second electrode.

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

a light conversion layer disposed on the display element layer and converting the light emitted from the first light emitting element.

10. The display device of claim 1 , wherein both the first electrode and the second electrode directly contact multiple light emitting elements under the convex shape of the at least one insulating structure.
