1. A color conversion panel comprising:
a substrate;
a plurality of banks disposed on the substrate, wherein the banks partition a first light emitting region, a second light emitting region, and a third light emitting region;
a first color conversion layer disposed in the first light emitting region, a second color conversion layer disposed in the second light emitting region, and a transmission layer disposed in the third light emitting region; and
a first reflective layer disposed to overlap the first color conversion layer and the second color conversion layer,
wherein the first reflective layer comprises a first layer, a second layer, and a third layer,
a refractive index of the second layer of the first reflective layer is greater than a refractive index of the third layer of the first reflective layer, and
the refractive index of the third layer of the first reflective layer is greater than a refractive index of the first layer of the first reflective layer.
