Abstract: A display device and a method of manufacturing a display device are provided. An embodiment of a display device includes a substrate; a first conductive layer disposed on the substrate; a first insulating layer disposed on the first conductive layer; a second conductive layer connected to the first conductive layer through a first contact hole in the first insulating layer; a second insulating layer filling an inside of the first contact hole; and a third insulating layer disposed on the second conductive layer and the second insulating layer. The first insulating layer includes a first region that overlaps the second conductive layer and a second region that does not overlap the second conductive layer, and a top surface of the first region of the first insulating layer is positioned higher than a top surface of the second region of the first insulating layer.

Abstract: A display device includes a first via layer on a substrate and including trench parts recessed from an upper surface of the first via layer, a first electrode and a second electrode on the first via layer and spaced apart from each other, a second via layer on the first via layer and including first openings partially exposing the first electrode, and a second opening partially exposing the second electrode, light emitting elements in the first openings of the second via layer and extending in a direction, and a third electrode on the second via layer. Each of the light emitting elements includes a first end electrically connected to the first electrode and a second end electrically connected to the third electrode such that the extending direction of the light emitting elements is not parallel to an upper surface of the substrate.
