Abstract: A liquid crystal display (LCD) panel employs a cholesteric polarizer which passes light of a first circular polarization, but reflects light of a second circular polarization. The LCD panel may be monochrome or color; in the color embodiments, several different color filters are used, each having one or more cholesteric polarizers tuned to a specific bandwidth in the visible spectrum. These polarizers replace dyed (neutral or dichroic) polarizers of prior art LCD panels, and provide improved color purity. The invention may be enhanced by providing a light recycling scheme whereby the handedness of the circularly polarized light reflected by the polarizers is changed and redirected back to the polarizers. This recycling scheme may also be adapted to provide an overhead projector having a high output polarized light source, particularly useful in conjunction with an LCD panel.

The first liquid crystal layer contains first cholesteric liquid crystal and has a reflective surface which reflects first circularly polarized light having a first wavelength. A first helical axis of the first cholesteric liquid crystal is tilted in a uniform direction over an entire area of the first liquid crystal layer. Each of a first outer surface of the first transparent substrate and a second outer surface of the second transparent substrate forms an interface which totally reflects the first circularly polarized light reflected in the first liquid crystal layer.
