A display is provided having a multiple view mode of operation and a wide angle single view mode. The display comprises a transmissive spatial light modulator which displays spatially multiplexed images in the multiple view mode and a single image with full resolution in the single view mode. The modulator has an input polariser which passes light of a first polarisation. A backlight has a light output surface with alternating first and second regions of parallel strip shape. The backlight is electronically switchable between the multiple view and single view modes. In the multiple view mode, only the first regions emit light containing the first polarisation. In the single view mode, both regions emit light containing the first polarisation.
