Display device

The invention relates to a display device. The display device includes: a substrate; an initialization voltage line on the 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 step portion and overlapping the initialization voltage line; an auxiliary pattern disposed on the low potential voltage line and forming a flat portion with a 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 end portions aligned on the first electrode and the second electrode; a first contact electrode in electrical contact with one end of the light emitting element; and a second contact electrode in electrical contact wi
