1. A display device comprising:
a substrate comprising first areas and second areas alternately arranged along a first direction in a plane view;
a first electrode and a second electrode on the substrate and spaced apart from each other along a second direction crossing the first direction, each of the first electrode and the second electrode extending along the first direction from a first area of the first areas to a second area of the second areas;
a light emitting element between the first electrode and the second electrode in the first area;
a first insulation layer located in each of the first area and the second area, a portion of the first insulation layer overlapping with the light emitting element along a thickness direction crossing the first and second directions being between the first electrode and the light emitting element and between the second electrode and the light emitting element along the thickness direction; and
a first contact electrode and a second contact electrode on the light emitting element and electrically connected to the light emitting element;
wherein the first insulation layer has a first thickness in the first area and a second thickness thicker than the first thickness in the second area.
