摘要： A polarized light extraction optical element (10) is formed by a light-transmitting base material (12) and a polarization separation layer (14) laminated thereonto, this polarization separation layer (14) being a liquid crystal layer made of a cholesteric liquid crystal. The thickness of the liquid crystal layer is smaller than the thickness that would be required to achieve a maximum reflectivity, so that part of one (L) of the right and left circularly polarized light components (R, L) is reflected with a reflectivity smaller than the maximum reflectivity.

摘要： The invention relates to an electro-optical cell (1) comprising a first (2) and a second (3) support member, an electro-optical medium (5) between the support members and an electrode arrangement (11, 12) on the support members such that an electric field can be applied, in the electro-optical medium, perpendicular to the support members, aligned with the support members or at an oblique angle (7) with respect to the support members. The electro-optical cell further comprises layers (14) of material with different dielectric constant between the support members in order to reduce the inhomogeneity of the electric field lines in the electro-optical medium. By having a layer of cholesteric liquid crystals between the support members, the electro-optical cell will function as a colour filter for varying applied fields. By introducing a particle suspension in a medium between the support members, an electro-optical cell is created that can be switched between a transmissive, reflective and partly deflective state.

摘要： A subtractive color liquid crystal display employing circular polarizers. In the subtractive color display each picture element has three liquid crystal switching elements. Adjacent to each liquid crystal switching element are a circular polarizer and 1/4 wave retarder plate combination. The circular polarizer and 1/4 wave retarder plate combination create a linear notch polarizer for an isolated and steep polarization band for each of the primary colors (red, green, blue). The notch polarizers are tuned to the particular backlight of the display in order to provide increased light transmittance and color gamut. The circular notch polarizers are preferably cholesteric liquid crystal silicones.

摘要： 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.
