STUDIES OF POLYMER-STABILIZED CHOLESTERIC LIQUID-CRYSTAL TEXTURE FILMS

Cells of polymer-stabilized cholesteric texture (PSCT) were fabricated with various polymer concentrations. The structure of the polymer net work and the electro-optical characteristics of the devices were studi ed. The result clearly demonstrates the polymer stabilization effect o n the liquid crystal domains in the cells. In addition, the hysteresis characteristics and the dielectric properties of the cells were studi ed as a function of the driving frequency. The results lead to the con clusion that the polymer enhanced hysteresis effect in PSCT cells is m ainly caused by the aligning effect of the polymer network.
