Abstract:
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.

Claim (Index 19):
A switchable display device according to  claim 18 , further comprising an anti-wetting surface provided to at least one of the switchable liquid crystal retarder, passive compensation retarder or input polariser of the spatial light modulator.
