| 摘要 | An electrophoretic reflective color display has a color filter on an electrophoretic display layer displaying black and white. A colored portion and a non-colored portion are provided in a pixel of the color filter layer, and the colored portion has a hue defined by specified values of chromaticity coordinates (a*, b*), measured with transmitted light using a D65 light source, in a chromaticity diagram of the L*a*b* color system. | ||

| 主权项 | 1. A reflective color display, comprising: a substrate; an electrophoretic display layer formed on the substrate; a light transmissive electrode layer formed on the electrophoretic display layer; and a color filter layer formed on the light transmissive electrode layer and including at least one colored portion and a non-colored portion in a pixel located on the light transmissive electrode layer, wherein the colored portion has a green hue defined by a chromaticity coordinate (a*, b*) in a chromaticity diagram of the L*a*b* color system satisfying −70≦a*≦−30 and −20≦b*≦20, where the chromaticity coordinate is measured with transmitted light using a D65 light source. | ||
