A display device including a substrate, a bank pattern extending in a first direction on the substrate, a first electrode on the bank pattern, a second electrode on the substrate, a first insulating layer on the first electrode and the second electrode, a light emitting element on the first insulating layer, and including a first end on the first electrode, and a second end on the second electrode, a first connection electrode contacting the first end of the light emitting element, and a second connection electrode contacting the second end of the light emitting element, wherein the bank pattern overlaps the first electrode and does not overlap the second electrode.

Display device

A display device comprises an initialization voltage line on a substrate, a first interlayer insulating layer disposed on the initialization voltage line, a low potential voltage line disposed on the first interlayer insulating layer, and having a stepped portion and overlapping the initialization voltage line, an auxiliary pattern disposed on the low potential voltage line and forming a flat portion with the stepped portion of the low potential voltage line, a second interlayer insulating layer disposed on the auxiliary pattern, a planarization layer disposed on the second interlayer insulating layer, a first electrode and a second electrode disposed on the planarization layer and spaced apart from each other, a light emitting element having ends aligned on the first electrode and the second electrode, a first contact electrode electrically contacting an end of the light emitting element, and a second contact electrode electrically contacting another end of the light emitting element.

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.
