Abstract: A pixel circuit layer of a display device is on a base layer and includes conductive patterns configuring at least one of a transistor, a capacitor, or a signal line. A first electrode and a second electrode are on the pixel circuit layer and are spaced from each other. A bank is on the first electrode and the second electrode and includes an opening. Light emitting elements are between the first electrode and the second electrode in the opening of the bank. In the opening of the bank, a space between the first electrode and the second electrode that are spaced from each other by a distance corresponding to a length of the light emitting elements is defined as a lane in which the light emitting elements are located. In a plan view, the lane does not overlap conductive patterns of the pixel circuit layer.
