ABSTRACT:
Thermal recording material has a plate- or film-formed polymer blend layer which is in a mutually dissolved transparent state below a certain temperature and in a phase-separated opaque state above said temperature. This thermal recording material is employed in an image display device, which is provided, in succession, with a recording heater movable along the recording material, an image display unit, a uniform heater and a gradual cooler for image erasure.
