    • A movable particle display (such as an electrophoretic display) in which a plurality of closed spaces are two-dimensionally disposed along a surface of the substrate, a plurality of particles contained in each of the closed spaces, and a reflection surface for reflecting light which enters each of the closed particles are moved inside a closed space, between a position at which they cover a reflecting surface and a position at which they are collected to expose the reflecting surface. At least a part of the reflecting surface diffusely reflects incident light with an intensity distribution having directional properties (i.e. non-isotropically). The intensity of the diffusely reflected light has an angular distribution such that: (1) the amount of light reflected toward the position at which the particles are collected is smaller than in the case when the distribution of diffusely reflected light is isotropic, and (2) the amount of light reflected away from the position at which the particles are collected is larger than that of light reflected towards that position.
    • 沿着基板的表面二维地设置多个封闭空间的可动粒子显示器(例如电泳显示器),每个封闭空间中包含的多个粒子和用于反射光的反射面 进入每个封闭的颗粒在封闭空间内,在它们覆盖反射表面的位置和它们被收集的位置之间移动以露出反射表面。 反射表面的至少一部分以具有方向性(即非均一性)的强度分布漫反射入射光。 漫反射光的强度具有角分布,使得:(1)向聚集粒子的位置反射的光的量比漫反射光分布为各向同性的情况少,(2) )从被收集颗粒的位置反射的光量大于向该位置反射的光的量。
