Claim:
1. An anti-reflection nano-coating structure comprising: a substrate that is flat or curved; a first coating layer that comprises a first oxide nanoparticle having a refractive index lower than that of the substrate and is disposed on the substrate; a second coating layer that comprises tapered nano-fillers including a titanium dioxide nanoparticle and is disposed on the first coating layer, wherein the tapered nano-fillers are aligned normally to the first coating layer; and a third coating layer having a refractive index lower than that of the substrate which comprises a plurality of second oxide nanoparticles, wherein the plurality of second oxide nanoparticles are disposed on an end of each of the tapered nano-fillers, wherein a diameter of each of the tapered nano-fillers decreases towards the first coating layer.
