Reflective Filter, Manufacture Method Thereof, and Display Device

Abstract

Disclosed are a reflective filter, a manufacture method of the reflective filter and a display device utilizing the reflective filter. The reflective filter includes a photonic crystal layer configured to reflect light at a specific waveband. By utilizing different types of photonic crystal regions in the photonic crystal layer to reflect light at different wavebands, it substantially increases the reflectivity of the reflective filter with respect to the ambient light and hence improves the contrast ratio of the display device.
