We have obtained a polymer wall-stabilized smectic A liquid crystal to be used for bistable flexible displays. The polymer wall structure optimally connects the two substrates together, thus providing maximum flexibility as compared to the polymer dispersed liquid crystal. Moreover, all the intrinsic bistable properties of the smectic A material are preserved. We analyzed the pixel performance and demonstrated very good electro-optical characteristics, high contrast ratio, and excellent stability of the states. The polymer wall-stabilized smectic A on flexible substrates has high potential to be used as electronic paper.
