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.

The device also include first and second alignment control structures formed, respectively, on the first and second substrates, for regulating azimuths of orientations of the liquid crystal when a voltage is applied thereto. The first and second alignment control structures each include a first line portion (extending in a first direction) and a second line portion (extending in a second direction, which is different from the first direction). The pixel electrode includes an edge extending in a direction different from both the first and second directions.

摘要： Disclosed is a transmissive liquid crystal projector carrying a vertical alignment liquid crystal device. The liquid crystal projector includes a liquid crystal panel (25), on the light incident side and on the light radiating side of which a light incident side polarizing plate (24) and a light radiating side light polarizing plate (26) are arranged, respectively. A first polarized light component in a light beam collected by an illuminating optical system is transmitted through the light incident side polarizing plate (24) and routed to the liquid crystal panel (25). An optical anisotropic device (45), tilted by a preset angle correlated with the direction of alignment of liquid crystal molecules in the liquid crystal panel (25), that is, a pre-tilt angle, is arranged between the light incident side polarizing plate (24) and the liquid crystal panel (25) or between the light radiating side light polarizing plate (26) and the liquid crystal panel (25). By so doing, a high contrast ratio may be maintained, while transmittance of the liquid crystal panel may be improved.
