Abstract:
1. An autostereoscopic display device comprising: a reflection layer for reflecting at least a portion of incident light as reflected light; a polarization conversion layer arranged over the reflection layer; an array of lenticular elements arranged over at least a portion of the polarization conversion layer and including a birefringent material; and an at least partially transparent diffusion layer arranged between the reflection layer and the polarization conversion layer, wherein light having a first state of polarization is arranged to pass through the lenticular element array without lenticular element focusing, and wherein the polarization state is transformed by the polarization conversion layer such that the reflected light has a second state of polarization arranged to pass through the lenticular element array with lenticular element focusing to provide different views to different viewing locations so that a first view is provided to a first location and a second view is provided to a second location.
