Utilization of the black conductive PPy film coated on the inner surface of the rear glass plate not only provided a convenient and economic method of fabricating CPD displays but also improved the contrast ratio by about 20%. By incorporating 20% of polymer into the chiral nematic mixture, the bistability and the viewing angle of the display were remarkably enhanced while the reflectance decreased from 89 to 29%.
