Display device and electronic device including the same

A display device comprising:

• a first light-emitting element located in a first pixel area;
• a first nanostructure array located in the first pixel area on the first light-emitting element, wherein the first nanostructure array includes first nanostructures repeatedly arranged along a first direction and a second direction crossing the first direction, wherein inclination angles of the first nanostructures with respect to the first direction change along the first direction;
• a second light-emitting element located in a second pixel area spaced apart from the first pixel area in a plan view;
• and
• a second nanostructure array located in the second pixel area on the second light-emitting element, wherein the second nanostructure array includes second nanostructures repeatedly arranged along the first direction and the second direction, wherein inclination angles of the second nanostructures with respect to the first direction change along the first direction.
