反射型カラーフィルタ及びこれを備えるディスプレイ装置

摘要

A reflective color filter may include a substrate, a photonic crystal layer including a plurality of photonic crystal patterns, and a light energy conversion device. The substrate may be between the light energy conversion device and the photonic crystal patterns. A reflective display device may include a liquid crystal layer having a light transmittance that is electrically controlled, a thin film transistor (TFT)-array layer including a plurality of TFTs for driving the liquid crystal layer according to image information, and a reflective color filter adapted to reflect light having a wavelength band corresponding to a photonic band gap from among light incident through the liquid crystal layer.
