Flexible reflective liquid crystal displays using stainless steel substrate

We have developed flexible reflective liquid crystal (LC) devicesÅ Å using stainless steel foil and polycarbonate substrates. We established an optical design method to make reflective LC devices by compensating for the phase retardation of the vertically aligned (VA) -mode LC and aluminum electrode with a polycarbonate substrate and polyimide film. Our method achieved a good contrast ratio, over 30:1, across a wide range of viewing angles. These results show that it is possible to realize high quality reflective displays with low power consumption and high flexibility.
