Disclosed herein is a thermal display system including a plurality of very small air-isolated semiconductor mesas or bodies, each of which contains a heater element so that when the heater element is energized a "hot spot" is formed at the top surface of the mesa to provide a localized dot of heat. By interposing a thin, flexible wear-resistant material, such as, for example, a thin paper or high-temperature plastic, between the mesas and a display medium, such as, thermal-sensitive paper, wear on the semiconductor mesas and residue buildup on and between the mesas may be substantially decreased.
