Abstract: A display device includes a substrate and a display element layer on the substrate. The display element layer includes: first and second electrodes extending along a first direction and spaced apart from each other in a second direction; and light emitting elements electrically connected to the first and second electrodes. The first electrode has a first convex portion convex toward the second electrode and a first concave portion concave in a direction away from the second electrode, and the second electrode has a second convex portion convex toward the first electrode and a second concave portion concave in a direction away from the first electrode. The light emitting elements includes a first and second light emitting elements, respectively close to the first concave portion and the second concave portion based on an imaginary extension line extending in the first direction between the first electrode and the second electrode.
