Abstract: In this paper, we propose a dye-doped LCD which is operated in the bistable chiral splay nematic (BCSN) mode for the superior dark state in the reflective mode. The operating principle of the proposed device is described in Figs. 1(a) and 1(b). We use the splay state as the initial state of the transmissive mode, whereas the ¥ð-twist state is used as the initial state of the reflective mode. By using the BCSN mode, the dark state of the reflective mode is improved because of change of the polarization state as well as the light absorption. In the transmissive mode, a fringe field is applied between grid electrodes and the bottom common electrode, whereas a vertical electric field applied between top and bottom common electrodes is used for the reflective mode.
