A Reversed‐Twisted Nematic (R‐TN) mode shows two stable states of splayed twist state and reversed twist state. These two states are switchable by applying the electric field of perpendicular or horizontal direction. The contrast ratio of the bistable R‐TN‐LCD is drastically improved by the optimization of the R‐TN LC cell.
