Claim 27:
28. A color transformation filter comprising:
a plurality of nanostructures included in a subpixel and spaced apart from each other, the plurality of nanostructures having a first refractive index;
a low refractive index layer provided adjacent to the plurality of nanostructures, the low refractive index layer having a second refractive index less than the first refractive index; and
a color transformation element included in the low refractive index layer,
wherein the color transformation filter has a multilayer structure, and
wherein the plurality of nanostructures in the multilayer structure are provided at a same position in each multilayer or are shifted in each multilayer in a horizontal direction, and
wherein lower surfaces of the plurality of nanostructures and a lower surface of the low refractive index layer in each layer of the multilayer structure are located on a same plane.
