Claim 0:
1. A display device comprising:
a substrate comprising a display area and a non-display area;
a plurality of pixels in the display area of the substrate, each of the pixels comprising a first electrode, a second electrode, a third electrode, and a fourth electrode spaced from each other and a plurality of light emitting elements electrically connected with the first to the fourth electrodes;
a plurality of first pads in a pad area of the non-display area of the substrate;
a first line, a second line, and a third line in the non-display area of the substrate, each of the first to the third lines being configured to receive a driving voltage;
a circuit board overlapping the pad area of the substrate and comprising second pads electrically connected with the first pads; and
a first contact electrode on the first electrode, an intermediate electrode on the second and the fourth electrodes, and a second contact electrode on the third electrode to connect to the plurality of light emitting elements to the first to fourth electrodes, wherein the intermediate electrode encloses the second contact electrode in a plan view,
wherein the first pads comprise a 1-1th pad electrically connected to the first line, a 1-2th pad electrically connected to the second line, and a 1-3th pad electrically connected to the third line,
wherein at least two lines of the first to the third lines are configured to receive the driving voltage having a first value, and
wherein the first to the third lines are to apply alignment signals to the first to the fourth electrodes to align the plurality of light emitting elements therebetween.
