A display device comprising:
- a substrate;
- a first electrode and a second electrode spaced from each other on the substrate;
- and
- a first light emitting element and a second light emitting element arranged between the first electrode and the second electrode,
- wherein the first light emitting element and the second light emitting element are electrically insulated from each other, and
- wherein the first light emitting element and the second light emitting element have different lengths.
A display device comprising:
- a substrate;
- a first electrode and a second electrode on the substrate;
- a first light emitting element located above the first electrode and the second electrode;
- a second light emitting element located above the first light emitting element and having a different length from the first light emitting element;
- an insulation layer between the first light emitting element and the second light emitting element;
- a first contact electrode connecting a first end portion of the first light emitting element and a first end portion of the second light emitting element to the first electrode;
- and
- a second contact electrode connecting a second end portion of the first light emitting element and a second end portion of the second light emitting element to the second electrode.
A manufacturing method of a display device comprising a substrate having a first alignment electrode on an upper surface thereof, the method comprising:
