This paper proposes the flexible color R2R Ch‐LC e‐papers. By adding photochiral dopant, single substrate flexible Ch‐LCD becomes sensitive to UV light. Therefore, UV exposure can cause the discontinuous change in the helical pitch of the Ch‐LC pixels to colorize the e‐paper. After being colorized, the color e‐paper can be electrically driven to update the displayed content. Furthermore, the image could become more vivid. And the gray‐scale image also could become more detail. In this paper, the 75 dpi and 4 bits gray‐level color R2R Ch‐LC e‐paper is implemented.
