A general film compensated reflective twisted nematic liquid crystal
display, device, system and method with phase compensation film set to
compensate the residual phase retardation of the liquid crystal in the
voltage-on state to increase the contrast ratio at a lower operating
voltage and decrease the color dispersion when used in reflective and
transflective liquid crystal displays. The phase compensation film set is
selected based on the twist angle and the residual retardation of the
liquid crystal layer, wherein the compensation film set has an effective
film phase retardation value and effective polarizer angle to cancel the
total residual phase to obtain an excellent dark state for achieving the
high contrast ratio.
