<p>A switchable autostereoscopic display device comprises a display panel (60) and an imaging arrangement (620 for directing the output from different pixels to different spatial positions to enable a stereoscopic image to be viewed. The imaging arrangement comprises a blue phase LC material. A controller switches the blue phase material to an isotropic state for the 2D mode and to a birefringent state for the 3D mode. This arrangement enables a switchable lens arrangement to be formed without alignment layers. This can give a high angle performance thin switchable arrangement.</p> |
