Abstract: A display device includes: a substrate having a display area and a non-display area; and a pixel in each of a pixel area in the display area. Each of the pixels includes: an insulating layer on the substrate and having an opening; first and second electrodes on the insulating layer and spaced apart from each other; a plurality of light emitting elements in the opening; a first contact electrode electrically connecting one end of the light emitting elements and the first electrode to each other; a second contact electrode electrically connecting another end of the light emitting elements and the second electrode to each other; a first insulating pattern on the first contact electrode; and a second insulating pattern on the second contact electrode. The first insulating pattern and the second insulating pattern are on the same layer and spaced apart from each other.
