This research presents thermally activated monochromatic reflective display produced by very simple method based on thermochromic pigment and its thermo-optical properties are investigated. The display exhibits maximum white reflectance of about 48%. The bright level of this thermochromic display (TCD) cell is continuously tuned by the temperature changes under adjusting the driving voltage to the TCD cell. It also showed a wide viewing angle above 80 degrees without any optical components. This display is considerable for applications where indoor or outdoor poster information must be presented clearly with low cost.
