[ I claim:] [1.] A heat-sensitive display for selectively displaying information depending on temperature, said display comprising:a substantially opaque polyester base layer;a heat-sensitive layer, said heat-sensitive layer including a support layer made of sheet material stabilizing a heat-sensitive material in dimensional thickness and uniformity, said heat-sensitive layer being configured and made of a heat-sensitive material selected so that said heat-sensitive layer is substantially colored and opaque at a lower temperature and substantially colorless and transparent at a higher temperature; andan information marking provided on at least one of said base layer and said heat-sensitive layer and positioned behind said heat-sensitive layer so that said information marking is not displayed when said heat-sensitive layer is substantially colored and opaque and displayed when said heat-sensitive layer is substantially colorless and transparent.
