1. A display device comprising:
a first pixel, a second pixel, and a third pixel that form one dot and display different colors;
a first light emitting element disposed in the first pixel, a second light emitting element disposed in the second pixel, and a third light emitting element disposed in the third pixel; and
a first color conversion area in which a first color conversion layer overlapping the first light emitting element is disposed, a second color conversion area in which a second color conversion layer overlapping the second light emitting element is disposed, and a third color conversion area in which a third color conversion layer overlapping the third light emitting element is disposed,
wherein the first color conversion area, the second color conversion area, and the third color conversion area have polygonal planar shapes having at least 5 sides, and
wherein a first length which is a distance between edges facing each other in a first direction in the first color conversion area, a second length which is a distance between edges facing each other in a second direction in the first color conversion area are different from each other;
wherein the first pixel and the second pixel are disposed in a first row and disposed adjacent to each other along a horizontal direction, the third pixel and the first pixel are alternately disposed along a vertical direction, the third pixel and the second pixel are alternately disposed along the vertical direction, and an imaginary line connecting a center of the first pixel, a center of the second pixel, and a center of the third pixel forms a triangular planar shape.
