methods , systems , devices and apparatus of using a reflective liquid crystal device for projection display operating at a reduced driving voltage and having an increased contrast ratio are disclosed . the reflective liquid crystal device comprises a first substrate , a second substrate with reflector means , and a twisted nematic liquid crystal layer between the first substrate and the second substrate . a polarizing beam splitter is placed outside of the reflective liquid crystal device and adjacent to the first substrate . by setting the entrance polarization direction of the polarizing beam splitter along the azimuthal angle of the linearly polarized eigenmode of the reflective liquid crystal device at the designed driving voltage , a perfect dark state is obtained , which leads to a high contrast ratio at the designed low driving voltage .
