Abstract
A privacy display comprises a spatial light modulator and a view angle control element that may comprise a first polariser that may be a reflective polariser, a liquid crystal retarder, a compensation retarder and an additional polariser. The layer of liquid crystal material is patterned with a mark. The display provides visibility of the mark in reflected light to an off-axis snooper but no visibility of the image on the spatial light modulator; and provides high visibility of an image with no visibility of the mark to an on-axis display user.
