A normally black reflective twisted-nematic mode is proposed for microdisplay application. This mode is based on the polarization rotation effect of a twisted-nematic liquid crystal. In the dark state, the cell exhibits a large gap tolerance and weak color dispersion. For twist angle ranging from 45degrees to 65degrees, the maximum normalized reflectance can achieve 100% through d/p (cell gap over pitch) ratio optimization. Particularly, when the twist angle equals to 52degrees, the normalized reflectance can reach 100% without any chiral dopant. The twist angle and polarizer angle also make important contributions to the bright state optical efficiency and dark state spectral bandwidth. (C) 2004 American Institute of Physics.
