ABSTRACT:
Discloses is a rewritable thin image display sheet, an image display apparatus and an image display system. In the image display system, a low-melting-point wax18with a magnetic powder16dispersed therein is held between a heat-generation layer12and a transparent layer14which are disposed spaced apart from one another, and a zone of the low-melting-point wax18corresponding to a pixel for image display is selectively heated and molted by the heat-generation layer12. Then, the magnetic powder16in the molten zone is displaced toward the transparent layer14so as to display a given image on the transparent layer. The rewritable thin image display sheet, the image display apparatus and the image display system can reliably display an image in a rewritable state while achieving a significantly simplified structure.
