Abstract

A color reflective display includes a substrate, an electrode pattern layer formed on the substrate, a reflective display-material layer formed on the electrode pattern layer, a light-transmissive electrode layer formed on the reflective display-material layer, a transparent layer formed on the transmissive electrode layer, and a color filter layer formed on the transparent layer and including an array of colored pixels. The color reflective display satisfies a following first formula when (0.54×C)−15 μm is zero or a positive value: (0.54×C)−15 μm≦D≦(0.54×C), and the color reflective display satisfies a following second formula when (0.54×C)−15 μm is a negative value: 0<D≦(0.54×C), where C represents a distance from the reflective display-material layer to the color filter layer, and D represents a distance between adjacent colored pixels of the color filter layer.
