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.
