Abstract
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.
