Abstract: A display device includes electrodes disposed on a substrate, the electrodes extending in a first direction and being spaced apart from each other, a first insulating layer disposed on the electrodes, light-emitting elements disposed on the first insulating layer, between the electrodes, a second insulating layer disposed on the light-emitting elements, the second insulating layer extending in the first direction, connecting electrodes disposed on the second insulating layer and the light-emitting elements, the connecting electrodes electrically contacting end portions of each of the light-emitting elements, and a third insulating layer disposed between the connecting electrodes. An end portion of at least one of the connecting electrodes overlaps another one of the connecting electrodes.

Abstract: A display device includes a first electrode and a second electrode which are disposed on a substrate and face each other. Light-emitting elements are disposed between the first electrode and the second electrode. Markings are formed on the first electrode in a first extending direction of the first electrode in a plan view.
