1. A display device comprising:
a circuit element layer comprising at least one transistor; and
a display element layer disposed on the circuit element layer, the display element layer comprising:
a first area comprising first, second, and third light emitting areas and a first non-light emitting area; and
a second area comprising fourth, fifth, and sixth light emitting areas and a second non-light emitting area,
wherein the display element layer comprises:
a first light emitting element to provide a first light to each of the first light emitting area and the fourth light emitting area;
a second light emitting element to provide a second light to each of the second light emitting area and the fifth emitting area;
a third light emitting element to provide a third light to each of the third light emitting area and the sixth emitting area;
a pixel definition layer having openings defined therethrough to overlap the first, second, third, fourth, fifth, and sixth light emitting areas, respectively; and
a first division pattern disposed in at least some of the openings, and wherein:
each of the fourth, fifth, and sixth light emitting areas of the second area comprises a plurality of sub-unit areas,
the first division pattern overlaps the second area and divides each of the fourth, fifth, and sixth light emitting areas of the second area into the plurality of sub-unit areas,
the second non-light emitting area of the second area comprises a first sub-non-light-emitting area surrounding the fourth, fifth, and sixth light emitting areas and a second sub-non-light-emitting area surrounded by the plurality of sub-unit areas of each of the fourth, fifth, and sixth light emitting areas and the first sub-non-light-emitting area, and
the pixel definition layer overlaps the first non-light emitting area of the first area and the first sub-non-light-emitting area of the second area and has a transmittance different from a transmittance of the first division pattern,
the display element layer comprises a first support pattern disposed on the pixel definition layer and surrounded by the first, second, and third light emitting areas of the first area or a second support member disposed on the pixel definition layer and surrounded by the fourth, fifth, and sixth light emitting areas of the second area, and
the first and second support patterns and the first division pattern comprise one of a polymer material and a silicon.
