Abstract

A display device includes light-emitting elements disposed on first and second electrodes, and having first end portions disposed on the first electrode, and second end portions disposed on the second electrode, a first connecting electrode extending in a first direction and disposed on the first electrode, the first connecting electrode being in contact with the first end portions of the light-emitting elements, a second connecting electrode extending in the first direction and disposed on the second electrode, the second connecting electrode being in contact with the second end portions of the light-emitting elements, and a connecting electrode pattern disposed on the first electrode, the connecting electrode pattern overlapping the first connecting electrode. The second connecting electrode and the connecting electrode pattern include a same material, and a thickness of the first connecting electrode is less than a thickness of the second connecting electrode and the connecting electrode pattern.
