Bistable chiral splay nematic liquid crystal display (BCSN LCD) is a memory type liquid crystal display using splay and

twist states as two stable states. When the cell thickness to pitch (d/p) ratio is 0.25, splay and

twist states have permanent memory time. However, when the transition from

twist state to splay state is caused by a fringe field, pixel regions show that the splay state is not perfect, but rather includes a contribution from the

twist state. In this paper, we propose a reflective BCSN LCD using

twist state in which the two stable states do not coexist. The fabricated reflective BCSN LC cell shows a high contrast ratio of over 30:1 and response times of 950 ms and 450 ms in vertical and fringe field switching, respectively. The proposed cell also shows wide viewing angle characteristics of

in left- and right directions.
