Popis:	We developed two-step UV exposure method to achieve high performance flexible cholesteric LC displays: first exposure to form polymer walls and second exposure to get colors. The dependence of the parameters such as monomer concentration, UV irradiation energy, and temperature was extensively investigated for clear polymer wall formation and high reflectance of the cholesteric LCDs. Good RGB color cholesteric LCDs were achieved by doping a photo-sensitive chiral dopant into the mixture of cholesteric LC and monomer and by irradiating UV light with appropriate energy. The approach for flexible color Ch-LC displays is discussed in detail.
