1. A display device comprising:
a substrate;
a first power line extending in a first direction on the substrate, and configured to transmit a first driving voltage;
a second power line extending in the first direction on the substrate, and configured to transmit a second driving voltage;
a first electrode extending in a second direction perpendicular to the first direction, to which the first driving voltage is applied;
a second electrode spaced apart from the first electrode and, extending in the second direction, to which the second driving voltage is applied; and
a light-emitting element between the first electrode and the second electrode, connected to a first contact electrode and to a second contact electrode, and having been aligned by a first alignment signal supplied to the first electrode via the first power line and a second alignment signal supplied to the second electrode via the second power line;
wherein the first electrode is electrically connected to the first power line and to the first contact electrode, and
wherein the second electrode is electrically connected to the second power line and to the second contact electrode.
