1. A display device comprising:
a substrate having an emission area and a non-emission area;
a first electrode and a second electrode spaced from each other on the substrate in the emission area;
a first insulating layer on the substrate in the emission area and the non-emission area and covering at least a portion of the first electrode and the second electrode;
a light-emitting element between the first electrode and the second electrode;
a first contact electrode on the first electrode and in contact with one end portion of the light-emitting element, and a second contact electrode on the second electrode and in contact with the other end portion of the light-emitting element; and
a first active material layer on the first insulating layer in the non-emission area and electrically connected to the first contact electrode, a gate insulating layer on the first active material layer, a gate electrode on the gate insulating layer and overlapping the first active material layer, and an one electrode in contact with at least one side of the first active material layer,
wherein at least a portion of the first contact electrode and at least a portion of the second contact electrode are on a same layer as the first active material layer.
