PDCLCDs (Polymer Dispersed Cholesteric LCDs) would be a good candidate of e-paper displays because they have excellent mechanical stability as well as bistability. In addition, PDCLCDs are adaptable to Roll-to-Roll processing, which enables to manufacture low cost displays. However, PDLCs have a big disadvantage that high voltage in general is needed to drive them. To solve the problem, we have developed PDCLCDs using newly developed low driving voltage cholesteric LCs, which provide conventional cholesteric LCDs with driving voltage of around 15 volts at cell gap of 4mm. In this paper, the experimental procedure and electro-optical properties of the PDCLCDs will be discussed.
