1. A display panel comprising:
a base layer including:
a first area;
a second area; and
a third area, the third area being disposed between the first area and the second area;
a circuit layer including:
a first intermediate insulating layer disposed on the base layer;
first conductive patterns disposed on the first intermediate insulating layer;
a second intermediate insulating layer covering the first conductive patterns;
second conductive patterns disposed on the second intermediate insulating layer; and
a third intermediate insulating layer covering the second conductive patterns; and
a light emitting element layer disposed on the circuit layer, the light emitting element layer including a first light emitting element and a second light emitting element disposed in
the first area and the second area, respectively, of the base layer, wherein the first light emitting element is electrically connected to one of the first conductive patterns through a first through-hole formed through the second intermediate insulating layer and the third intermediate insulating layer,
the second light emitting element is electrically connected to one of the second conductive patterns through a second through-hole formed through the third intermediate insulating layer,
a smallest width of the first through-hole and a smallest width of the second through-hole are substantially equal to each other on a cross-section, and
the first conductive patterns are spaced apart and disposed in the first area and the third area of the base layer.
