We have proposed two new optical configurations to improve the light transmittance of a fringing-field-controlled multidomain vertically aligned liquid crystal display (FEF-MVA-LCD). We show that, by using a MVA-LC panel sandwiched between two circular polarizers, improvement of the maximum transmittance by more than 30% is achieved in comparison to the transmittance of a conventional panel configuration using two linear polarizers. We also demonstrate that further improvement of the light efficiency was achieved by combining a cholesteric liquid crystal film with a circular polarizer. This method using cholesteric liquid crystal and circular polarizer films may be the most effective for the improvement of the luminance of a FEF-controlled MVA-LCD panel.
