There is disclosed a multi-view autostereoscopic display device comprising an image forming means arranged over and in registration with a view forming module. The image forming means has a planar array of light emissive display pixels arranged in rows and columns for producing a display, the display pixels being spatially defined by an opaque matrix. The image forming means may, for example, be a LCD display panel. The view forming module is configurable to function as a plurality of view forming elements arranged in the width direction of the display device, each view forming element focusing the light output from an adjacent group of the display pixels into a plurality of views for projection towards a user in respective different directions. The view forming module may, for example, be an array of lenticular lenses. The geometry of the view forming elements defines a substantially periodic inter-element variation in the width direction of the display device, for reducing brightness non-uniformities in the views. The inter-element variation may, for example, be provided by varying at least one of the widths, the focusing powers and the relative positions of the geometric axes of the lenticular lenses in the width direction of the display device.
