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 waxwith a magnetic powderdispersed therein is held between a heat-generation layerand a transparent layerwhich are disposed spaced apart from one another, and a zone of the low-melting-point waxcorresponding to a pixel for image display is selectively heated and molted by the heat-generation layer. Then, the magnetic powderin the molten zone is displaced toward the transparent layerso 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.
