New electro-optical schemes for display and projection system applications on the basis of cholesteric liquid crystals (CLC) are discussed. Reflective properties of CLC can be utilized to achieve controlled spectral selectivity through control of spectral distribution of polarizational states of the illumination. Low reflectant CLC-mirrors can be combined to form a resonator with higher reflectance. A chiral mirror is discussed with huge rotation of the polarization of reflected light. Fan-shaped distribution of color by polarizations turns out to be possible.
