Autostereoscopic display device

An autostereoscopic display device comprises a display (103) having an array of display pixels (105) and a view forming arrangement (109) of elongate elements which have a long axis which is slanted at an angle α to the column pixel direction, and the elements have a pitch of P times the width between pixels of the same color in different columns. The pitch P is selected to be: P=0.5·k·(1+S2) in which S=tan α, and k is a positive integer. This arrangement enables the resulting image projected in respect of each view to have a uniform and regular distribution of pixels across the image. This improves the visual appearance of the views.
