— In reflective color STN-LCDs, it is necessary to achieve achromatic representation in single-polarizer STN-LCD modes. We propose an optimization method for the optical components of single-polarizer STN-LCD modes in order to achieve achromatic representation. By applying this method, it is shown that a contrast ratio of more than 20 can be achieved in the normally black (NB) mode. Furthermore, we prove that the normally white (NW) mode can be realized as well as an NB mode which is usually used in current reflective color STN-LCDs. Comparing the viewing-angle characteristics of the NW and NB modes, it was found that those of the NW mode are better than those of the NB mode. Particularly, high reflectance can be realized even at larger viewing angles in the NW mode.
