Claim 19:
20. A display device comprising:
a display panel comprising a display area in which a plurality of pixels are located, and a non-display area in which a first line, a second line, and a third line to which a driving voltage is to be applied are located, the non-display area comprising a pad area in which a plurality of first pads are located;
a circuit board in contact with at least one side of the display panel, and comprising second pads electrically connected with the first pads;
a printed circuit board in contact with at least one side of the circuit board; and
an anisotropic conductive film located between the display panel and the circuit board and between the circuit board and the printed circuit board,
wherein the first pads comprises 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 each of the pixels comprises:
a first electrode, a second electrode, a third electrode, and a fourth electrode spaced from each other,
a plurality of light emitting elements electrically connected with the first to the fourth electrodes, 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 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 fourth electrodes to align the plurality of light emitting elements therebetween.
