MANUFACTURING METHOD OF OMNI-DIRECTIONAL REFLECTOR

摘要

A method for manufacturing an omni directional reflector is provided to form a low reflective index layer with a conductive nano rod by using a self-shadowing region and an oblique deposition method. A transparent conductive low refractive layer(31) is formed in one side of a reflective layer(32). The transparent conductive low refractive layer includes a plurality of conductive nano rods. The air is filled in a spacer between the plurality of conductive nano rods. The plurality of conductive nano rods are obliquely deposited in the reflective layer with a predetermined angle. The plurality of conductive nano rods form the self-shadowing region in a deposition process. The transparent conductive low reflective layer has the lower reflectivity than the plurality of conductive nano rods. The thickness of the transparent conductive low reflective layer is proportional to the 1/4 wavelength of the light.
