PROBLEM TO BE SOLVED: To provide an image display device which can reliably display an image in a rewritable state while achieving a significantly simplified structure, and to provide an image display system. SOLUTION: In the image display system, a low-melting-point wax 18 with a magnetic powder 16 dispersed therein is held between a heat-generation layer 12 and a transparent layer 14 which are disposed spaced apart from each other, and a zone of the low-melting-point wax 18 corresponding to a pixel for image display is selectively heated and melted by the heat-generation layer 12. Then, the magnetic powder 16 in the molten zone is displaced toward the transparent layer 14 so as to display a given image on the transparent layer 14. COPYRIGHT: (C)2008,JPO&INPIT
