Abstract
A dielectric-based reflective color filter includes a substrate layer capable of light reflection; and a dielectric layer formed on the substrate layer. The dielectric layer includes a plurality of dielectric units configured by a first structure extending in a first direction and a second structure intersecting the first structure and extending in a second direction. The plurality of the dielectric units is arranged on the substrate layer so as to be spaced apart from each other.
