1. A display device comprising:
a thin film transistor layer comprising at least one transistor on a substrate;
a first electrode on the thin film transistor layer and connected to the at least one transistor;
a second electrode spaced from the first electrode on the thin film transistor layer in a first direction that is parallel to the substrate;
a plurality of light emitting elements connected to the first electrode and the second electrode; and
an electrode pattern at a same layer as the first electrode and the second electrode and overlapping the plurality of light emitting elements in a thickness direction,
wherein the electrode pattern is disposed under the light emitting elements, and insulated from the light emitting elements, the first electrode, and the second electrode,
wherein, in a plan view, a length of the first electrode, a length of the second electrode, and a length of the electrode pattern extend in parallel to each other in a second direction crossing the first direction, the second direction being parallel to the substrate, and
wherein, in the plan view, the electrode pattern in its entirety is spaced from at least one of the first electrode or the second electrode in the first direction.
