1. A display device comprising:
a base part;
a semiconductor light emitting device disposed on a first region of the base part; and
a plurality of assembly electrodes extending along one direction on the base part and to which a voltage is applied to dispose the semiconductor light emitting device at a pre-set position on the first region,
wherein the plurality of assembly electrodes are disposed not to overlap a thin film transistor,
wherein the plurality of assembly electrodes comprise a first protrusion protruding from the first region toward the semiconductor light emitting device, the first protrusion overlapping the semiconductor light emitting device,
wherein the plurality of assembly electrodes further comprise at least one of a second protrusion protruding toward a second region and a third protrusion toward the first region and the second region,
wherein the display device further comprises a storage capacitor disposed in the second region, and
wherein the storage capacitor is disposed between the second protrusion and the third protrusion.
