Abstract: A display device includes a substrate, a transistor, an interlayer insulating layer, a first conductive line, a pixel electrode, a passivation layer, a common electrode, and a light emitting element layer. The transistor overlaps the substrate. The interlayer insulating layer overlaps the transistor and includes a first groove. The first conductive line is electrically connected to the transistor and is at least partially disposed inside the first groove. The pixel electrode is electrically connected to the transistor and overlaps the first conductive line. The passivation layer is disposed between the pixel electrode and the first conductive line and directly contacts at least one of the pixel electrode and the first conductive line. The common electrode overlaps the pixel electrode. The light emitting element layer is disposed between the common electrode and the pixel electrode.
