We propose optical configurations for reflective liquid crystal displays that can be applied to most of display modes with the 0° twisted state. Optimized configuration can be obtained by using a cell with quarter‐wave retardation or with half‐wave retardation. Especially, a half‐wave reflective cell provides the highest brightness in the bright state as well as the lowest brightness in the dark state. By fabricating reflective half‐wave cells, we demonstrated high brightness as well as the high contrast ratio of 20:1.
