Abstract
A display device includes a substrate including a display area including pixel areas and a non-display area adjacent to the display area; and a pixel disposed in each of the pixel areas. The pixel includes a sub-electrode, a first conductive line, and a second conductive line on the substrate; a first insulating layer over the sub-electrode and the first and second conductive lines; first to fourth electrodes on the first insulating layer; a second insulating layer over the first and second electrodes to completely overlap the first and second electrodes, the second insulating layer exposing the third and fourth electrodes; light emitting elements between the first and second electrodes; a first contact electrode on the first electrode; and a second contact electrode on the second electrode.
