2 . The display device of claim 1 , further comprising a plurality of connecting wires extending from the second area to the first area and comprising a transparent conducting oxide,
wherein a number of the plurality of connecting wires arranged on a first row crossing the first outer column is different from a number of the plurality of connecting wires arranged on a second row different from the first row.

3 . The display device of claim 1 , further comprising an intermediate pixel circuit arranged in the first outer pixel area,
wherein the second display element further comprises an intermediate display element arranged in the first outer pixel area and electrically connected to the intermediate pixel circuit.

4 . The display device of claim 3 , further comprising:
an intermediate data line extending along the first outer column and electrically connected to the intermediate pixel circuit; a first data line extending along the first outer column in parallel with the intermediate data line; and a first pixel circuit arranged adjacent to the first outer pixel area in the third area, and electrically connected to the first data line.

5 . The display device of claim 1 , wherein the second area further comprises a second outer pixel area overlapping a second outer column different from the first outer column and spaced from the first area,
wherein the display device further comprises: a second outer data line extending along the second outer column; a second inner data line electrically connected to the second outer data line and extending along the first inner column; a second outer pixel circuit arranged in the second outer pixel area and electrically connected to the second outer data line; and a second inner pixel circuit arranged in the first inner pixel area and electrically connected to the second inner data line, wherein the first display element further comprises a second outer display element overlapping a second inner column different from the first inner column, wherein any one of the first display element or the second display element comprises a second inner display element at least partially overlapping the first area and overlapping the second inner column different from the first inner column, wherein the second outer display element is electrically connected to the second outer pixel circuit, and wherein the second inner display element is electrically connected to the second inner pixel circuit.

6 . The display device of claim 5 , further comprising:

7 . The display device of claim 5 , further comprising an additional data line electrically connected to the second inner data line and extending along the second inner column.

8 . The display device of claim 1 , further comprising a third display element arranged in the third area and including an emission area smaller than any one of an emission area of the first display element or an emission area of the second display element,
wherein a width of the second area at the first outer column is less than a sum of a width of the first area and a width of the second area at the first inner column.

9 . The display device of claim 8 , wherein the first area and the second area further comprise a plurality of pixel areas arranged in a first direction and a second direction perpendicular to the first direction,
wherein the plurality of pixel areas comprise: a plurality of first pixel areas overlapping a first virtual extending line extending in the first direction; and a plurality of second pixel areas overlapping a second virtual extending line extending in the first direction and adjacent to the first virtual extending line, and wherein a difference between a number of the plurality of first pixel areas and a number of the plurality of second pixel areas is a multiple of four.

10 . A display device comprising:
