<P>PROBLEM TO BE SOLVED: To provide an image display device using a micro-mirror device that is easily downsized. <P>SOLUTION: A reflective display device includes a micro-mirror device in which a plurality of mirrors 2 capable of changing a reflection angle are disposed and parts 1 where different light beam flux from each other, parallel light beam flux emitted from different curved surfaces from each other, and light beam flux constituted by a light beam group with a common orthogonal curved face including both a light beam group collected from two or more directions and a light beam group spreading toward two or more directions enters each one of reflection surfaces among the plural mirrors of the mirror 2 group. <P>COPYRIGHT: (C)2012,JPO&INPIT |
