1. A display transfer structure comprising:
a substrate comprising a plurality of wells; and
a plurality of light emitting elements disposed in the plurality of wells,
wherein the plurality of light emitting elements have a rotationally asymmetric planar shape,
wherein the plurality of wells respectively have a planar shape different from a planar shape of each of the plurality of light emitting elements,
wherein a first well of the plurality of wells comprises a first area and a second area partially overlapping each other,
wherein a first light emitting element among the plurality of light emitting elements is disposed in the first area or the second area,
wherein the first area and the second area respectively have a planar shape corresponding to a planar shape of the first light emitting element,
wherein the first area and the second area are connected each other and a size and a shape of the first area is same as a shape and a size of the second area,
wherein the first well and a second well among the plurality of wells that are adjacent to each other are included in a subpixel,
wherein the first well and the second well are disposed in an arc shape with respect to a predetermined central axis perpendicular to the substrate, and
wherein a first electrode pad and a second electrode pad of the substrate have an arc shape or ring shape with respect to the predetermined central axis.
