An auto-stereoscopic display device which addresses the problem of how to provide an improved three dimensional effect without degrading the resolution of the views. The auto-stereoscopic display device comprises: image forming means having an array of display pixels for producing a display; view forming means positioned in registration with the image forming means and having an array of view forming elements, the view forming elements each being configurable to focus the outputs of groups of the display pixels into a plurality of views projected towards a user in different directions; and view deflecting means positioned in registration with the view forming means, the view deflecting means being arranged to selectably change the directions in which the plurality of views are projected towards user. The view deflecting means comprise at least one birefringent prism having a first refractive index for light having a first polarization direction and a second refractive index for light having a second polarizat
