The polymer stabilized cholesteric texture (PSCT) light valve is constructed using a cholesteric liquid crystal/polymer composite. It exhibits bistability at a bias voltage and is used to make a multiplexed display on a passive matrix. We optimized the performance of the PSCT valve by adjusting the cholesteric pitch, the polymer concentration and polymerization condition. We also studied the performance of the PSCT valve at various temperatures. Using the PSCT material, we have successfully constructed a projection display with high brightness and high contrast.
