Reflective LCDs are greatly needed for the application of personal information appliances. Among various reflective LC modes currently proposed, we focused on the cholesteric texture (CT) mode for its high reflectance at a specific wavelength range and simple cell structure, that is, only a light absorption layer is required for the CT cell. To realize a high information display with the CT mode, an active matrix driving such as TFT is necessary. The low driving voltage is required for an active matrix driving. In this report we tried to reduce the threshold voltage of CT mode LCD by the adjustment of the cell design and the cholesteric liquid crystal materials.
