摘要: A privacy display comprises a spatial light modulator and a compensated switchable liquid crystal retarder arranged between first and second polarisers arranged in series with the spatial light modulator. In a privacy mode of operation, on-axis light from the spatial light modulator is directed without loss, whereas off-axis light has reduced luminance. The visibility of the display to off-axis snoopers is reduced by means of luminance reduction over a wide polar field. In a wide angle mode of operation, the switchable liquid crystal retardance is adjusted so that off-axis luminance is substantially unmodified.

摘要: A liquid crystal device includes: an element substrate; a counter substrate disposed opposite to the element substrate; a sealing material disposed between the element substrate and the counter substrate; and a liquid crystal layer disposed on an inner side of the sealing material and containing liquid crystal. The element substrate includes an alignment film configured to align the liquid crystal and an ion-adsorbing first adsorption film disposed in contact with the sealing material. The alignment film includes a first vapor-deposited film and a second vapor-deposited film disposed between the first vapor-deposited film and the liquid crystal layer. The second vapor-deposited film and the first adsorption film include a column of which a long axis direction intersects a thickness direction of the liquid crystal layer. A thickness of the first adsorption film is thicker than a thickness of the second vapor-deposited film.

摘要: The Kerr effect depends very strongly on the temperature and is associated with high operating voltages. The present invention relates to an electrically controllable optical element which comprises a cell (D) filled with a starting mixture (K) and having two substrates (1a, 1b) and a conductive layer (2a, 2b) applied onto the inner surface of the respective substrate (1a, 1b), wherein the starting mixture (K) comprises a mixture of dipolar, rod-shaped molecules (5) and semi-mesogenes (4) as active constituents, and wherein the starting mixture (K) forms a thin layer having a wide-meshed, anisotropic network (9) produced by photo-polymerization between the structured or/and flat conductive layers (2a, 2b), which are applied onto a substrate (1a, 1b), in a thin-film cell (D). According to the invention, an optically active surface profile (O) is incorporated on the inner surface of a substrate (1a or 1b) or into the substrate (1a or 1b) or both substrates (1a and 1b).
