ABSTRACT:
A novel display material is disclosed, which comprises a material layer containing a dye and a supporting electrolyte.
The material layer is capable of solid-liquid transformation. The coloration and discoloration of the layer are effected by oxidation reduction reaction of the dye by applying current to the material layer in liquefied state.
The display material may be used as electrochromic display and thermosensitive recording paper.
