A configuration of a display device capable of color display is obtained. The display device includes a plurality of rod-shaped light-emitting elements each of which includes a semiconductor and which emit light beams having wavelength distributions different from each other, and alignment electrodes (12). The alignment electrodes (12) include a first electrode pair (12a), a second electrode pair (12b), and a third electrode pair (12c). The plurality of rod-shaped light-emitting elements include a first rod-shaped light-emitting element, which is arranged so that one end of the first rod-shaped light-emitting element is adjacent to one electrode of the first electrode pair while the other end is adjacent to the other electrode of the first electrode pair, a second rod-shaped light-emitting element, which is arranged so that one end of the second rod-shaped light-emitting element is adjacent to one electrode of the second electrode pair while the other end of the second rod-shaped light-emitting element is adjacent to the other electrode of the second electrode pair, and a third rod-shaped light-emitting element, which is arranged so that one end of the third rod-shaped light-emitting element is adjacent to one electrode of the third electrode pair while the other end of the third rod-shaped light-emitting element is adjacent to the other electrode of the third electrode pair. Lengths R1 to R3 of the first to third rod-shaped light-emitting elements and distances d1 to d3 of the first to third electrode pairs (12a) to (12c) satisfy the following relationships. d1≦R1<d2, d2≦R2<d3, d3≦R3.
