Display device and manufacturing method thereof
A display device according to an exemplary embodiment of the present disclosure comprises an insulation layer on a substrate and having a groove concave in a direction toward the substrate; a first reflective layer on at least a portion of the insulation layer; and a display element layer on the insulation layer and the first reflective layer, the display element layer including a light emitting element overlapping at least a portion of the groove.
1. A display device comprising:
an insulation layer on a substrate and having a groove concave in a direction toward the substrate;
a first reflective layer on at least a portion of the insulation layer; and
a display element layer on the insulation layer and the first reflective layer, the display element layer comprising a light emitting element overlapping at least a portion of the groove,
wherein the display element layer includes:
a first electrode extending in a first direction different from the direction and electrically coupled to the light emitting element; and
a second electrode spaced apart from the first electrode in a second direction different from the first direction and electrically coupled to the light emitting element,
wherein the groove is filled with an insulation material,
wherein the insulation material forms a flat surface with the first electrode and the second electrode, and
wherein the light emitting diode is on the flat surface.
2. The display device of claim 1 , wherein,
the first reflective layer is on the groove and overlaps the light emitting element.
3. The display device of claim 1 , wherein,
each of the first electrode and the second electrode has a portion overlapping a portion of the groove.
4. The display device of claim 1 , wherein,
a distance between the first electrode and the second electrode in the second direction is less than a width of the groove in the second direction.
5. The display device of claim 1 , wherein,
a distance between the first electrode and the second electrode in the second direction is the same as a width of the first reflective layer in the second direction.
6. The display device of claim 1 , wherein,
the first and second electrodes and the first reflective layer include a same metallic material.
7. The display device of claim 1 , the display element layer further comprising:
a first bank on the first electrode; and
a second bank on the second electrode.
8. The display device of claim 7 , the display element layer further comprising:
a second reflective layer on the first and second banks.
9. The display device of claim 1 , further comprising
an intermediate layer between the first electrode and the insulation layer and between the second electrode and the insulation layer, and having an opening overlapping the groove.
10. The display device of claim 9 , wherein,
a distance between the first electrode and the second electrode in the second direction is the same as a width of the opening in the second direction.
11. The display device of claim 9 , wherein,
a width of the opening in the second direction is less than a width of the groove in the second direction.
12. The display device of claim 1 , the display element layer further comprising:
a first contact electrode on the first electrode and configured to electrically connect the first electrode and the light emitting element; and
a second contact electrode on the second electrode and configured to electrically connect the second electrode and the light emitting element.
