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.

Abstract: A display device includes a substrate including a display area and a non-display area, and pixels disposed in the display area. The pixels each include first electrodes, second electrodes spaced apart from the first electrodes, and light emitting elements disposed between the first electrodes and the second electrodes. The first electrodes each include a closed loop of a polygonal shape in some sections.
