    Abstract: A method of manufacturing a display device includes: forming a first electrode on a substrate; forming an insulating layer on the substrate and on the first electrode;
    providing light emitting elements in the insulating layer, each of the light emitting elements having a long axis and a short axis crossing the long axis and being configured to emit light; aligning the light emitting elements such that one end of each of the light emitting elements faces the substrate and the long axis of each of the light emitting elements is arranged in a direction from the substrate toward the insulating layer; patterning the insulating layer to form an insulating pattern exposing another end of each of the light emitting elements; and forming a second electrode electrically connected to the exposed other end of each of the light emitting elements.

    Abstract: The display device includes: a substrate; a first electrode and a second electrode that are disposed on the substrate and spaced apart from each other; a first insulating layer disposed between the first electrode and the second electrode and covering the first electrode and the second electrode; and a light emitting element disposed on the first insulating layer and extending in a first direction. The light emitting element includes: a first side extending in the first direction; a second side opposite to the first side; a first lateral side connecting first end portions of the first and second sides; and a second lateral side connecting second end portions of the first and second sides. Each of a first interior angle and a second interior angle, which are formed by the first side and the first and second lateral sides, is an acute angle.
